A nice challenge....

Greetings to all you unpackers.
It's been quite a while since I posted something here. But now I have found a nice challenge for people interested in unpacking targets. Go to hxxp:\\www.autodebug.com and download Autodebug pro 3.6 for windows.
I have tried to unpack it, and seems to succeed but when I run it it crashes.
It is packed with both Aspack and PeCompact. First with pecompact then wrapped once more with Aspack. It is no problem solving this two things, but then the fun starts. There are calls to IsDebuggerPresent, and there are some other stuff that makes the program crash via int3 exceptions. But after solving these things, the program still don't run properly. It just excits after a few seconds. When you run the prorgam in Olly, it detects bp's (at least in the code section). When you succeed solving this in Olly, you will see that it crashes in a place where it seems that some code is overwritten when you try to run it in a debugger.
Anyone interrested in taking a look?
And for the record: I don't care in breaking the serialprotection. I'm just after unpacking it until it runs just fine.

regards,
