Fanart won't change

First post on this forum and just wanted to say thanks for a great piece of software. Apologies if a solution to my problem has already been posted, but I searched and didn't come across any helpful info. I haven't had any issues up until now, but I am seeing some problems trying to change my fanart. This is using an older build of XBMC on an Xbox.

I scraped my media and got everything set up the way I like it. However, when I changed fanart using MC, it wouldn't show up unless I manually changed it in XBMC by browsing to the movie folder and selecting the new fanart I downloaded. Not a big deal, but a bit of a pain.

However, in trying to change my fanart for the Lord of the Rings trilogy, it simply will not change, and what's even more odd is that when I navigate to the movie folders in XBMC, the fanart file thumbnail is still the old picture. However, when browsing the movie folder on my computer's hard drive using Windows 7, it is the new fanart I downloaded.

Fixes attempted so far with no change:

- Refreshing each film in XBMC.
- Deleting the movies from my library and re-adding using XBMC.
- Deleting everything in each movie folder other than the films, then re-scraping everything.
- I also cleaned my library each time I attempted a fix.

I thought of deleting the database file in XBMC, but am not sure of exactly what this woulld do so opted not to until I sought help on this forum. Any advice would be appreciated.

Thanks,
