Hello Ron,

I need a little bit of information:

1) Where are you storing the files that you are importing? 
2) Have you changed the storage location in MobileSheetsPro or are you using the default location?
3) Are all of the files PDFs? If so, have you tried changing Settings->Display Settings->Render Preference to see if one PDF library works better than the other?
4) Are you cropping the songs during importing? If you uncheck the auto-crop option, does that have an impact?
5) Is the error you are seeing shown after you load the song on the gray background? Or are you actually seeing a dialog box pop up?

Hopefully we can figure out what is going on quickly.

Thanks,
Mike
