looks like no one has a solution, i personally would use winamp to get the info and play the music in wmp. when you use winamp to update the info wmp will be able to read the tags and info also.
when i used to use wmp i would fetch the albumart myself by using google images. as for track info give winamp a whirl you wont be dissapointed,
dont have winamp as your default player, open an album in winamp click the now playing tab and select all the tracks , right click and select send to /autotag, follow the prompts to change the info and it will update your tags , ,close winamp open wmp and the library should update with the new tag info.
sorry i dont have a fix for the wmp issue, but this is a workaround . you will see how easy it is to use in comparison to wmp .
