This was quite fun. I attempted at first to look at things with ollydbg, but once I fired up Reflector it was a simple matter of looking at the checkme functions.

As a novice I found this quite fun :)

But remember the rules matey: NO PATCHING ;)
Get me a good solution + keygen, and I`ll say we`ve both been satisfied :=)

I'm stuck at the signature. I guess I'm missing something, 'cause I don't know how to create a valid one without the private key...

Okay, rules have changed!
If its too hard for you to make a keygen only, its now allowed to make a little patch on the side aswell - but the patch has to be in the keygen aka keygen+patch in one!

Why I ask for both in one, is cuz this crackme was firstly intended for the ones that can code and crack well and not the newbie level!

So enjoy!
