Image Missing Image Name = sg.mask

HELP!!

I have xp and I switched computers awhile back, I transfered my pictures and

thought everything was fine then yesterday I was playing on a casino site

and everything was fine. I then transfered new pictures from my camera, I

then went in to edit them and noticed that I couldn't so I downloaded a few

different photo editors to try didn't like them so I uninstalled them. Later

in the day I went back to the casino and I was able to log on and play at the

reg. slot machines but when I went to a free slot tournament it froze and

then to day when I try to go to the casino I get this error message

Image Missing:

Image Name = sg.mask

File Name = ../games\slots/images/reelshading.png

I have uninstall the casino download and reinstaled it and it does the same

thing, also I play 3 different casinos with these free tournys and I can't

play on any of them.

I downloaded a registry cleaner to try to find this but it didn't work

If anyone knows what I did and how to fix it, it would be great
