Zapperier

Hopefully this is the right area for this... But I'm having what I gather is some sort of ID conflict, and another topic (http://www.minecraftforge.net/forum/index.php?topic=6375.0) seemed to mention it, but while luacs1998 mentioned that I cannot seem to find this "older version". I'll put the crash-report below, I'm running a bunch of mods but it didn't work when any or all of them were up to date. And a bit of the Log from the event (when enabling the Log in Magic Launcher)... Also, I've removed the config files, reran it, and also deleted the whole folder. This is using the new Magic Launcher. Please reply with semi-detailed instructions (I already know I have a problem here). Thanks.
