I have a problem running version 1.7.2 of Forge: The launcher just downloads something then restarts in a (seemingly) endless loop. Apparently it's walways different files, sometimes the same files with different version numbers. Here's the crash log (only one restart) It worke3d fine yesterday, but I did install NEI since then. As mentioned, I run Forge 1.7.2 Cheers, Burger
