I don't see any logs in my .minecraft dir. Infact, there is not ForgeModloader folder at all (although there is an empty mods folder)

 

[LexManos]

Its not 'ForgeModLoader' folder, it's just the 'logs' folder, Vanilla minecraft puts logs in there as well.

However, this issue is caused by it not being able to find the base of a class that it trying to patch.

More information should be obtainable in the log from the logs folder.

However as a guess on the fix, go into the versions folder delete both the vanilla 1.7.2, and the forge folder.

Run vanilla 1.7.2 and then reinstall Forge. To make sure that you have a vanila 1.7.2 base jar.
