I seem to have a similar problem. After restoring my MS back up file to the new pro version, I find that quite a number of PDF files seem to be missing from the imported songs. The songs are all there, but once I open them, some of them show an error message telling me that the corresponding PDF file can not be found. I used to have that same problem sometimes on the old MS, but ususally, after a couple of attempts the file did actually load. Not sure, what the problem is and how it can be fixed.
