Well... The picture says it all but this is what happens: When I open the editor, it shows me the GSTLAE Logo and after that it shows me that window pitch black. If someone can help me, please let me know and thanks a bunch in advance! 
Edit: Ive already used this editor a while ago (like 1-2 years ago with a nvidia GTX 460 and now I have a RX 480). For some reason now it doesnt work and its the same OS (W7 64 bits).
2nd Edit: Ive noticed that when I open it and press Ctrl + O it lets me open the ROM but still black screens so that means it IS working. The interface is the one thats not showing for some odd reason.
