TouchShield Slide image upload

I am having major problems with uploading 91 bitmaps to my TouchShield Slide. The first 34 images are no problem. They are uploaded correctly. But then the screen background gets grey (in stead of black). It looks like the images are still uploaded, but I cannot use them afterwards. My 91 images are around 800kb in total. This looks like a buffer overflow of some sort. I tried to hack the FlashFileSystem.ccp file but I had no luck at all.

Does anyone else have this issue too? Any help is deeply appreciated after all the time that I have spent on this issue.
