I had the same issue too. It happens with some nvidia cards
Right click on the ET shortcut and go to properties and add +connect <insertipaddresshere> in the target line
It doesn't have to be an IP address, it can be just any number. (for example +connect 0) This will make ET attempt to connect automatically to the set ip address upon launching and for some reason it gets you out of that grey screen.

Alternatively you can just connect to a server through xfire
