That number after the filename is very strange. Is the file name literally "Haste to the Wedding.pdf 164995804427"? I'm wondering if that number after the file extension is causing some unusual problems. Also, does the file actually exist at the location that MobileSheetsPro is looking for it under? I'm guessing the file may not exist there.  If your file did not have that number originally, that means MobileSheetsPro may have tried to copy the file to the SD card and it failed to do so.  If you try to swap again, do you receive the same error?
