easy, but it is nice crackme imho...

I agree, This crackme should be rated as 1 for several reasons:
1. the packers aren't modified in any tricky way.
2. the anti-tracing tricks doesn't really fool IDA.

There is an other issue , some of the valid serials can't be entered because the dialog box is too small for the width of some chars (try using several 'A's for example)

anything packed with anti-debug tricks no matter how simple should be labeled a 2

Thank you for compliments :) It's a nice try for newbies who are not yet very fimilair with unpacking and want to try something on their own, because the UPX sections are modified, no auto-unpack can be done.

Furthermore, the crackme is double-packed, it's also packed with PEPACK can be unpacked usual unpacking way.
