Ultima 7 Issues

[Sith-Avenger]

HI. I recently downloaded and ran Ultima 7 using the exult software. As the screen was very small I tried using the command to change the window size (ctrl KP+/-) but the game went very pale in colour, I tried changing the gamma settings but nothing happened. I re-started but the graphics were the same pale colour so I uninstalled exult and deleted my Utima files and started form scratch, but now I get no graphics at all, just music and a black screen, and so cannot start the game... :tai:

Any help would be appreciated

Many Thanks
