then something most be wrong with your SICE or not well hidden .. then SICE detection reboots your machine somehow ... at OEP there's NOP data 9090909090 ... the loader will write CC at 00401380
when you do bpint3 SICE should break and then you'll be able to write back 90 then you'll be able to dump .. maybe you're trying with the DEMO version?? i wrote this was for full version .. i haven't try with the DEMO.. OEP location most be difference for it.
anway you can try any other method to be able to reach OEP and dump.. now you know where is OEP
