2013-04-08 22:51:12 [iNFO] [sTDOUT] Exiting mod pack

[miniboxer]

Try clicking the gear icon next to the tekkit lite pack icon, then clicking "reset pack."

[marioman_1998]

How come i've never noticed that before. I would completely remove tekkit from my computer and re-install. Thanks mini

Yes, let's ignore the error and use a workaround...

yeah well that didnt work for me. i went there and there was no reset button. and i even completely deleted the launcher and all the files for it and i still got the fatal FML error message. also it says the problem is with the forge mod loader. if it is will i have to get all the mods out of it and delete the forge mod loader?
