there are guys working on it to crack this. the current status is, that crc check is cracked, but there are problems with the dejavu, might be cracked within the next few days, stay tuned.
at this point, compliments to the developer (I guess, this could be very good revengs :) but I might be wrong )
so it's nearly cracked, but to all other devels: you should secure your soft in that way
so it will remain exciting
