I think there's a bug in your keygen.
You perform the following steps:
Step 1: name= a, and click Gen, check it with Funny KeyGenMe --> good
Step 2: name= abc, and click Gen, check it with Funny KeyGenMe --> good
Step 3: name= a, and click Gen, check it with Funny KeyGenMe --> wrong

You should use ZeroMemoru Function

@quangredlight: You were correct, i wasn't zeroing the naem buffer, it's corrected now and reuploaded. Something i normally do but overlooked this time, oops. Thanks for the heads up.

To make a keygen you have to study how to program validates a serial then code a small program yourself that will produce valid serials based on the criteria found from examining the program. There is no quick fix unfortunately.
