I have the same thing and with the tut of MEPHiST0 to detect armadillo's version, my program was protected by armadillo 3.75b.

So there is WriteMemory with 2 bytes protection and after You can rebuild IAT finding magic jmp but after it seems to have anti dump with jmp in armadillo code which is not in dump(code splicing) and perhaps nanomites.

Someone did he already have this protection?
