We always need a full log to find such issues.

Okay, here's the full log on pastebin. Thanks!

Hi,
New alpha doesn't fix this previous issue.

Note that the directory in question has the following structure:
X:\usenet\tv\cowboy bebop\Cowboy Bebop - Session 01 - Asteroid Blues (720p) (ACFADD3A).mkv

Damn, I forgot.
I thinks it's an issue with votes or rating value for this tv show. Please check both values. Votes should be integers only (no spaces or other characters), rating should be a double value, that means 5.8 and not 5,8.

Edit:
Do you have allready have an NFO for the file? If yes, please upload the tvshow.nfo and the episode NFO.

PS: Session 01 is not a correct tag to mark the file as episode 1. You have to use the official Kodi naming: Link
