DzSoft Perl Editor 5.3.0.1

Type : Perl Editor
Protection : ASProtect -- Serial
Tech : Loader

Crack :

I think cracking involves luck ... it was realy hard to find the reg check in this new version as they have put it in some other thread or something .... it was just hard to trace and also it was packed with ASProtect.But i think it was born to be cracked.
As i told it was realy hard ... used many techniques but failed ... An idea came to my mind "why not dump the program running on the pc and use w32dasm".We can't use w32dasm on exe file as it is packed.Will w32dasm work with the dump file ... i don't know what programs real OEP is.Will it work ..."who cares ..lets do it".So i did was to do a plain dump of the running program using PEditor.And used w32dasm on this dump with all section flags set to E0000020 of this dump file[other wise w32dasm will not show you any thing].
To my surprise it worked .... search for string "unregistered" ... now just look few lines up you can see the reg check call ....
