I have the same error I hate it. My friends are always talking about how cool this is. I didn't even delete the FML files they just weren't there when I got the launcher.

I found a fix, just delete the FTBBETAA folder and the launcher and reinstall the launcher and launch should reinstall all the mods with fml!

Moved to the correct section.

Yep. Generally just deleting the install folder (where you put FTB.exe/.jar) and making it new works like a charm glad you got it going!

I had the same problem with Optifine. But it was 1.5.1 so it is irrelevant. Anyways glad to see you got it working.
