Is there a file called ui_mp_x86.dll in your jaymod folder? And also one should be inside etmain folder.

If not, there is something wrong with the installation. You did grab the ET: Legacy Windows 32-bit installer, right?

If there is no ui_mp_x86.dll in jaymod folder (and whatever other mod you want to play) you need to open the jaymod pk3 and extract it from there. The installer of ET: Legacy should automatically download the ET files and work it's magic, but perhaps something went wrong

If you are fine with downloading it from a mirror, I have uploaded the jaymod ui_mp_x86.dll on my server here: http://mstk.eu/f/ui_mp_x86.dll
(MD5: A664B87536FAFD76966B68718A0B28FE, VirusTotal report)
Chrome will warn about the file because it's a .dll, check VirusTotal link above, it's clean.

If you are not fine with downloading from my mirror, you can open the jaymod-2.2.0.pk3 in WinRAR and extract the ui_mp_x86.dll file from there to your ET: Legacy /jaymod/ folder.

PS. Also try running ET: Legacy as admin. As a last resort you can try installing ET: Legacy from the binaries instead of the installer, as suggested here: https://board.twcclan.org/thread-6852.html
If it comes to this resort, I can guide you with the binary installation method!

Try to delete the whole folder of et.
And then, reinstall the game, re-upload the etkey and let's restart with 0xp. 18k isn't that much. If you are playing very often, you will recover quickly. (Playing agains bots with cover ops is a very good way)
Good luck !
