Describe the issue Check functionality on MPF UI needs some additional error messages (better indication of what is missing.)

I dumped an audio CD as IBM PC by accident; so I figured, I'll use check to generate a new submissioninfo file, but I kept getting this error:

After a bit of discussion, it turned out that the program needed to have all the files that MPF zips up present in the folder so it can do its thing, but it doesn't actually say that in those specific words. I suggest changing the text to read "Make sure all required dump files are in the same folder" or something similar.

Additionally, since it overwrites any submissioninfo files that may be in the folder, it should warn the user before it begins doing anything, after selecting a file to process (a suggestion, of course.)

To Reproduce No steps needed.

Expected behavior See above

Screenshots None needed
