Smartgaga Black screen when enable VT

yesterday I installed LD player its say enabled VT so I enabled it.. after I just open smartgaga normally then emu open black screen auto on-off ... so I disabled VT but not working and I trying reset my PC but still getting black screen..... please help me

sorry i do not know much about smartgaga cause i am using gameloop, But maybe the problem is due to LD player. Did you tried to uninstall the LD player and check the smartgaga if it works?

Reinstall SmashGaGa maybe solve this problem
