You need to add some Infos if you wish that the developer changes something.
Which Windows? 3.1/3.11/95/98/ME/2000/XP/7/8/8.1/10? (Windows 7 and lower does not get support)
Which Computer? CPU, Board, Ram, Graphic Card
Have you downloaded a second Time to Test?
Are all drivers up to date? All Windows Updates?
Have startet the Game as Admin to Test?
Thats relevant Informations for the developer. ^^
