error in freearc [help]

[rafikhan]

i was trying to compress mass effect 3 game files about 9.0gb & i did compress those file with freearc ( -mx -maxsrep -maxprecomp )
the size of the arc became 4.1GB Perfect size but when i was trying to unpack it freearc says ''Arcextract.hs.154.24.36 non exhaustive patterns in lambda error'' that was very heartless sentense to me. I spend 4 hour to compress those files.
someone help me to fix this bug.
