hmmmm... found a bug in the download part of the program ("TheTvDB v3.0 B.Download Images.mscr"). If you run the program for a series that you have already genrated sheets for before, it can happen that you don't get sheets for newly added episodes. I am testing a simple fix to the download script, which seems to fix the problem. For now, for those interested and knowledgeable, you can try by commenting out the if/endif statements as per below. Or you can wait for the next revision in which the fix will be included.
# If (Not(FileExists(StrZipPath)))
strUrl = "http://thetvdb.com/api/BE74C9BE57F37CEF/series/" & arySeriesID[intChoice] & "/all/en.zip"
