Hey Fresco, there are a few anti debug checkpoints, NtQueryInfo, IsDebuggerPresent, etc.

You have forgotten to strip the crackme of debug symbols, everything's visible.

Well then it should make it a lot easier for you to post a solution : )

Some of the plugins might work in Olly but not all.

IAT is still in tact though, so maybe try starting there as all (except one or two) anti debug tricks are reliant on win32 API calls. Don't want to reveal too much, but pay attention to the LoadLibrary calls, the rest should be transparent.

Thanks for the feedback Fresco, I appreciate it. Stay tuned for my next crackme!

loizos - Cracking this program without reversing it would be like frying eggs without heating them, maybe it's possible but I don't think so : )

I'd recommend that you google 'lena's reverse engineering tutorials' and start with the first one, they are well done and you'll learn a lot.

serial is based on Node-Name and IP (the mac is retrievd too, but i did not investigate if/how it is incorporated into the serial)
Basic serial format is as follows:
UserName[3]||IP_addr[1]||8-Numbers||Node_Name[0]

Interesting Functions are at 0x4091f8 and 0x408f1a
