    Somewhere on your hard drive (obviously not going to say, the quest is with you) was generated, a file .ini containing the correct serial. If it is easier for you, find that file. large file, but is due to skin utilized. Good fun.

    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
