My first crackme. It contains mostly known anti-debug and exploits. Should serve as a nice starter for beginners.

No, not IsDebuggerPresent. :P

Very nice crackme like for the newbies, I've got pleasure from resolving it and had be glad to see your next crackme! The solution is on its way :)

A very well-done man. :) This crackme is pretty under-rated. (I must admit, cant even solve by myself *cough*) So far you are the only person who solve it. ;) (or the only person who gave full attention).

So what OS you are running? The SizeOfRawData patch is supposed to be an anti-IDA trick, and it works well on my OS.

Sorry man, on the clean machine with Windows XP, Service Pack2 it works very well!
But I have used Windows Xp SP1 with SoftIce and DeamonTools installed, maybe this stuff got my system crashed.
