MC version is 1.2.5, Forge 22.214.171.124, FML 126.96.36.199, Mo' Creatures 3.6.2(that's version for mc 1.2.5).
It's definietly not problem of mo' - i investigated a little, tried installing mods, not installing mods etc. Tried even older version of forge, without success. Every time i run i see http://screenshooter.net/9767455/WoWScrn_062612_152915
Then I get on this forums, learned a bit and run minecrafterrortest.bat...and you know what? The game works fine.
So, what's the difference between normal loader and this bat file?
forge log: (generates after running bat file, otherwise there is no new log)
Running the game using this bat file is not really a solution, as long as i want to play online.
