If you go to Settings->About on the tablet, what version of MobileSheetsPro is listed? I just exported a setlist to Dropbox, then used Import->Dropbox to import the .msf file and encountered no problems. What type of tablets are you using and what Android OS version are they running? If you go to Settings->Storage, have you changed any of the default settings? If you download the file from Dropbox and use Import->Local File, does the .msf file work in that case? I may need to take a look at the .msf file.

As a side note, are you using the FastSpring version on each tablet since different musicians are utilizing them?
