Again a small puzzle.
Your task is to find a correct serial. As the code is in C# .NET, the source can be obtained by Reflector.

The only obfuscation here is my coding style and the Visual Studio Compiler :D

Rules: NO Patching, NO brute forcing.

You may exploit some flaws in checking function if you can find any!

cause deducted a lot of combination until there were only few, then hand-tried the combination

thanks
