Other FTB (archived by John)

Today,ive took alot of hours in fixing Cracked Feed The Beast Launcher 1.3.4v which was actually a failure at ending..
Let me know if you guys know how to fix this problem because ive didnt found a way to push myself to TWC mc server and i found this 1 much more difficult to fix than any other launcher...
----------------------
I started to Use the version 1.3.4 FTB Launcher and download FTBLite 2 modpack,
Since ive downloaded some files like versions,libraries,assets and FTBLite folder pack from the launcher..i used to get alot of errors and very strange crashes after i click on "Launch"...
At first when i finished downloading the modpack,i clicked on Launch and i thought everything is going fine and Minecraft game will pop up but not..
The launcher and console suddenly dissappeared after i clicked on "Launch" in few seconds....i checked the Task Manager and i dont see the launcher's process is running...and i was thinking that maybe it got crashed somehow...

So i opened the launcher back and it always pop ups me for an update to version 1.3.5 and i did update it..
but there was also another problem in it,It fails to launch the mod pack,

I reinstalled the launcher back,
Downloaded the file stuff and the mod pack again..
but i knew that the launcher and the console will disappear if i click on "Launch" so i did another thing..
I clicked on "Options" Tab and clicked on "Force Update"
and then i clicked on "Launch"
It started to download some new files from the Modpack,i felt like something different is happening right now and after the download finished...i see some errors appeared at console and freezed the launcher and the launcher didnt crashed but freezed and the console shows the answer:-

=======================
Google is my freind But i dont see alot of fixes for FTB Launchers,there is alot and too much of different errors occuring for "Cracked Launcher"ofc,
Other mincraft launchers like normal minecraft launchers,vanilla etc are more easy to fix because their crashes,bugs,errors are known and is fixed easily but for FTB..i dont see few problems got solved and not that much of peoples use FTB(I am not sure),i sent this error to thier supporting site and i hope i get answers by supporters but if not and if its late then i think i cant get through server..
Some says that dont update ur java to version 8
but then i got confused and gave up.

things like this shouldn't be discussed here, can lead to legal problems

Seems it can't connect. To what? I have no clue.
Maybe FTB blocked your launcher.

I believe putting up download links for cracked launcher would lead to legal problems. Limited support should be fine.

Uploading n downloadin cracked stuff could lead to legal problems.....

@ Moanraker

It Seems that Java fails to connect one of its own servers not sure but i can clearly see that the connection for the protocols are also failed..

Probably i have 2 Basic problems for this Launcher

1)If i update it to 1.3.5v, the launcher will fail to launch..
2)When i click on "Launch" the launcher will freeze in a second and will do nothing but gives the errors in the console(the one that is in the screenshot)
-----------------------------------------------------
Ive found something that caused the launcher to stop launching when updating to 1.3.5v,
I also told that at 1.3.5v,the console and the launcher will disappear in a moment when you click on "Launch"
i opened the LauncherLog txt file on the FTB Folder and ive readed the last line,
=============================================

=============================================
As u can see,i was trying login several times and the console and the launcher disappears everytime but the LauncherLog says the problem:"Failed to use Mojang's Authentication Library"
-----------------------------
Maybe the problem is optifine..
I inserted optifine 1.6.4 HD_CU in to the 1.6.4 Jar file and i think that caused the problem,not sure....
+ I also made a support to Their Supporting Site but non of their answers are correct and somehow there aint no good help :S !
