No doubt it crashes on 98 -you set the image base directly in DOS area ('98 uses the area below $4).

Yah crashed on my 98 too... I have recently installed 98 and so sorry that I couldn't try the new crackme which is rated so high....

did you read readme.txt before complaining?

I'm not complaining -just observed this when opening it in LordPE.
It's quite hard, I don't think I can solve it -anyway, anti-shadowed Olly check too, i'm delighted :)

i got OEP .. Why doesn't run on Olly and IDA ?

deroko r u cracked it by Soft-ice? ;)
MaxM

?? I'm commenting the key-checks in IDA right now. Dump it in Olly and then analyse it in IDA.
@konstAnt: want the dumped file in rapid for opening it in IDA? With commented database? ;)
