Nobody has even submitted a solution yet?

The aim is to analyse the encoded file after finding a valid user id.

Core things you need to use:
* Brute forcing (or a lucky guess)
* Dynamic analysis while it's running.

Bonus points for dumping the assembly of the license checking routine.
Extra bonus points for writing a c.enc file generator.

Nice one :) Not too hard, but hard enough for someone starting off reversing, like me.

You may leave your comment, thoughts and discuss this crackme with other reversers here.
