Hi, sorry the Mozart item was a red herring I was looking at my own support files, so i did have a problem there but now it is working okay for me.
Thanks for the support files, unfortunately there is nothing much in the logs to indicate the cause of issue. Could you try the following:
Go to Preferences:Support, and set Debug Log Level and Debug IO Level to Finest

Rerun Match to One album task
Then go back to Preferences:Support, and set Debug Log Level and Debug IO Level back to Warning
Then in case the issue is related to your files could you send me the music files for a folder you are trying to match to see if I can replicate the issue here, I will then delete the files afterwards.
