Nevermind my previous reply, I found a working version of Project Beta and Project Alpha. Go to the dev page and download the patched Alpha. Copy the gameinfo.txt from that, replace the Beta's with it, and replace the word Alpha with Beta throughout the replacement.

I had fixed Project-Beta and Project-Alpha. Those Portal mods, that where so good! I decided to upload the fix versions here. Then I found Project-Alpha was already fixed. So, if you want Project-Beta give me your email address and I'll email it to you when I have the time.
