I recently switched from Windows 8 Release Preview 64-bit back to Windows 7 Professional 64-bit. On Win 8, I had a MInecraft .jar that I had installed Forge onto and had working perfectly. After the switch, I just copied the .jar from the Win 8 HDD and loaded it with Magic Launcher. After the Mojang logo, Minecraft crashed and I got this error report:

I have done nothing to change the .jar and would really like to have Forge working again.

I have also done that on another fresh jar. No luck. :/

Never mind. The 1.4.6 update cleaned up this little problem quite nicely. Thanks for the help anyways though.

I am actually having another problem with Forge now.
