asterix,
Thank you very much~!

The DLL was packed by aspack 1.08.04, so I unpacked it by
unaspack1.08.04 ! but the dll was not loaded into memory after unpack!
then I re-packed it by aspack1.08.04 but it was not loaded into
memory too !

--summary--
if original DLL -> loaded success
after unpack -> not loaded
after repack -> not loaded

also when debugging with softice ! I do step by step F8,
I can see code changing automaticly
Example) next code was 'ADD ...' but after F8 the code was changed 'CMP.,.,'

I give up cracking !
The program with powerful anti-debug,anti-diassem surprised me !!
Sorry terrible english !
