Sorry, may be, You are already aware off my minor problem. If so, excuse me and don't hesitate to erase this redundant message!
What happens is:
If Autopar is on and a downloaded file with "Umlauts" (ÄÖÜßäöü) in the file-name given by the upper has a par2 -error, the file will be fixed using the par2 - files as it should, but is given a new name with some "Chinese" letters in it instead of the umlauts. These files with the new names are not longer recognized as members of the par2 - set and so the automatic repair fails.
Its up to me than, to change the names of the repaired files manually and Autopar will properly finish it's job.
As I remember, I'm using Newsbin since 2005 (maybe longer) and I think, You did a very good job. Congratulations and good luck!
