cracking jcreator, is it difficult?

i foudn that, there is one group released the oader/patcher for this program many times again and again since the old version, but most of them failed....just wondering that this program is a little bit difficult than the others? for peid its said "armadillo 1.xx-2.xx (overlay)" seem to be nothing much different than the others program.

i heard someone said GE2001.exe is the debugger to debug its main program....

i'm a beginner, dont know much about this...any answer would be appriciates...thank you!
