The new Eastern Front patch has caused my game to stop working!

I was planning on playing eastern front tonight, and downloaded the latest patch in order to play with the new Brits faction. However, when the loading bar came up, it asked me to 'insert my company of heroes CD,' which i already had in! So i took it out and inserted it again, and hoped for it to validate... but it still said that 'it could not verify media.' Any solutions? Would you recommend to ReInstall?

I had some issue like that above, when installing 1.3 through the "update" option. I don't recall the precise details of it, but I solved it by uninstalling EF (using EF uninstaller), downloading the complete 1.3 installer, and reinstalling EF.

thanks alot, but how do you get to the uninstaller? i have no idea where to find EF uninstaller...

It's inside CoH directory, it's called "uninstaller.exe".
