Either it doesn't work for your computer
Windows Vista. XP or 7?
32 or 64 bit?
---download the things listed in topblasts first post
go back to it
you need to patch some files and get the d3dx_42.dll thingy im not sure so go double check
i get this error aswell o.o
Hmm, I'm not getting and error(win7 64) and I'm using perx also
Just remember to run everything as admin.
Try disable UAC and firewall.
Good luck!
