    While trying to figure out another very easy crackme I was messing with VB. I ended up making my own CrackMe (very first!!!! ) This is very easy, initially it was too easy, first BP and serial was sitting in your face lol, so I added an extra compare (hint) Rules; NO PATCHING! This is too easy to Patch Serial Fishing is Acceptable on 1 Condition - When Posting your serial, you must also Post the Process you used to get the serial Keygenning is Ultimate Goal!

    Here is a challenge for all. Some time ago, I coded an (freeware for medical purposes) application which was never cracked. Too stupid, not worth bothering or too difficult ?!? Dunno ... but I hope you'll tell me. BTW, a registration scheme was only implemented to keep track of people's use (free registration). To comply with forum rules, I have grabbed the registration scheme and made a ReverseMe from it. Everything is allowed : serialfishing, patching, brute forcing ... the ultimate goal is a keygen. The only nag in the real stuff is when clicking the "Register" button. This reverseMe has more to make it easier. Each time an action is required, the registration sc…
