So, I tried loading a Portal mod yesterday. They worked fine before, but now I get a white screen and then the mod crashes. Can anyone tell me why this is happening?

steampipe happened;
Basically all files were moved and changed etc;

In case you don't want to read the whole thread (even though I highly recommend you to read it - we are trying to fix everything that was ruined by Steampipe), just check this link out.You can find there a fix for mods like Rexaura.

I had the same problem, but i figured out how to install them anyway. I made a tutorial how http://www.youtube.com/watch?v=fsVX547MPY4&feature=youtu.be
