Challenge of Reverse Engineering

Back after a weekend with lectures.....Another simple example. After of finalized. I found a small bug.....but purposefully, I resolved to leave it with this bug. Maybe give a cheer more for anyone trying to solve it. I'll await the gentlemen with their solutions, and soon I'll post my keygen, good fun and good luck.

Rating: Easy / Medium This is my first ever crackme/keygenme/keyfileme. It is programmed in .net (VB but in Reflector they all look the same ;-) ) It needs .net 4.0 Client Profile. It is obfuscated but its easy to remove and I think its not made much harder. Make a working keyfile for the Enterprise or Ultimate versions or better make a keyfile gen. Maybe do a tut to show how this protection could be made better (it could). BB KeyFileMe01.zip
