There is no fix for this feed the beast team dont know what causes this problem...

i have managed to fix it on ftb lite by moving all the files of ftb lite to another folder (named the same) , i don't know why and how this worked but it seemed to fix it for me! , however still does not work for mindcrack which is very frustrating!
