I FINALLY GOT IT TO WORK
I'm not sure exactly what made it work but i read somewhere online that gmk8 games needs c++ Redistributable. Coincidentally, an unrelated thing (a cnc generals fanpatch lmao) got me to install them, I randomly tried opening the game 2 days later and the game worked. I have no other idea for what could have made it work.
So for those who are getting the file seems corrupted error, try installing Visual C++ Redistributable (x86) 2005, 2008, or 2010.
It could also be a DirectX thing. Try installing "DirectX Runtime June 2010" too.
As for my thoughts on the actual game. It has yachie so an instant 5/5 on theme.
