This does appear to be a memory problem.
This is telling me that you are using to large of media and should use lower a resolution of your images.
I use images that are up to 300 KB in size for use in FTM, Word PowerPoint and etc. This makes them much easier to manage.
If I need to produce a print larger than a 8 1/2 x 11, I will use the original file that I made the reduced copy from.
