failed to run emGine on Windows8 Pro

Hi all, please help me.

I could not run emGine successfully on Windows 8 Pro.
I tried the compatibility mode too, but failed.
I dont know what happens, but the system tries to open it and stops everything. And my system pretends like i never asked it to run the software..! I cannot move even a step further if I fail to run it. Being reluctant to use cracked softwares, I have emGine as the only option..please help me...
