I was playing on an older version for a while (1.4.7 with custom launcher and custom directory).. but i was pretty much on the latest content.. now i wanted to try getting the latest versions of the mods and of course they need the latest forge version... so i got my minecraft to 1.5.2 downloaded everything and prepared everything... tried installing forge via magiclauncher and manually adding to minecraft.jar added the mods in mod/coremods folders and tried starting... magiclauncher brought up some error about invocationtargetexception and incompatibleclasschangeerror while starting via normal launcher got stuck in loading screen close to the end at the "Done Loading" part (getting a screenshot if you want)
log from the minecrafttester.bat:
heres the full log of the magiclauncher test:
edit: just in case... i tried both with only forge... thats the result
