I am not sure how deleting the files would allow it to work since the exe is loading up the eleckey dll and would then trigger its protection mechanism unless you bypass it.Just to investigate further, where did you download it? Maybe I downloaded some other version which was already modified and for which removing a few files was enough...? I downloaded it from this thread from the guy who said "no bj needed"
EDIT : well ok now thats weird. I restarted my computer and it stopped working for me as well! Now I'm clearly curious how wtf is going on
Edit 2 : apparently you also have to leave this file : Ekag20nt.exe. I'm gonna check again from a freshly extracted .rar. Yep it works now
For what its worth, I tried it didn't work for me.
