[HAFMC]

ok so long story short :/ through some fluke of miravle i managed to get unleashed server running there the other night through some hair pulling and trial and error... somehow...someway it worked.... so i was all happity...decided to add MAMC+ or whatever its called to get plugins to work as well but it messed up the server... so i reinstalled everything from the ground up, renamed serverjar file to FTB-Beta-A and what not and im getting the GODAWFUL BS ERROR AGAIN!!!! Anyone know how to fix this ? cause last time was pure fluke..... and yea i tried deleting openperiphreals....no go....
