Two recurring errors in Track Performance... completely lost as to why. (case 12671)

[skklogw7]

I keep getting these same two errors for (what I think) is every one of my trials (see the errornote.txt attached):

Elapsed Time: 99284ms, block 3, trial 38, stim 7, Error 53, File not found or incompatible stimulus format (e.g., images must be 8-24bit color .bmp) , on line 330, during CreateSurfaces of Form DDFullScreen

Elapsed Time: 99286ms, block 3, trial 38, stim 7, Error 5, Invalid procedure call or argument--may be a problem loading a stimulus due to its format, on line 590, during CreateSurfaces of Form DDFullScree

Any look at my file and your input would be MUCH appreciated.

Thank you!
