Why is it only works under the debugger (windows xp sp1)

Probably because of mentioned anti debug tricks. If debugger detected then check is altered.

@tomkol, 3ton means that the program runs fine with the debugger (after fixing), but the program crashes when running it OUTSIDE of the debugger.

If before patching crackme works fine than he did something wrong. Or some anti debug trick crashes it with given name/serial combo outside debugger.

I think the second case is more likely, it crashes for me on Windows 7 Virtualbox (without patching, vanilla), but oddly enough, when I run it on Wine using Linux, there are no problems.... strange, it might be a problem with DLLs then...
