Why do we need luck ?

It's packed with reflector and It's easy to restore.

Hi FarJump,
is your crack-me packed with the new .Net Reactor 4 or did you modify it by hand in some way? Seems that nobody was able to crack it so far...

Andu,
No, didn't modify it by hand.. used NR 4 beta 2 (beta tester). At least I'm not able to crack my own but packed crackme and it already survived the first days. Waiting for a crack..

Not because It's hard ! I almost finished it in 10 minutes but I got bored in the end.

Kurapica,
Did you dump and fix the assembly? I have tried this way but the relevant methods are empty.

This is the CrackME file that can be opened in reflector and Ildasm, you won't find the check algo here because some sections are compressed.
