I think I find a piece of protection scheme that looks new for me...
I'm relatively "new in the business" so I would
apreciate any hints or sugestions from an experienced
cracker.

Well, I tried to crack a russian soft, serial based
registrations but not this is the problem.

I tried first with Softice, but a message box tell me
something like "Debugger detected, program aborted",
then everything crashes, including Softice, general
protection fault.I switch the Faults off but no use,
"illegal operation" message windows show up on the screen.

Then I tried Wdasm, despite the fact there is no
readable string in program files but this one
failed too , ridiculous...

As the authors said , the program is written in C++
and I suspect it uses some of the debug() functions
of the windows API but my knowledges about that
ends here.

What can I do ? From where shoud I start ?
Thank you.

If you're using win 9x, you should start by using Frogsice (get it at http://www.programmerstools.com/) which can bypass every kind of softice detection.

Then, you should read articles about debugger detection ('Meltice' is the easier to understand and is used by Softice itself .
