A week ago all my songs on recent tracks played started showing the wrong album cover, the album cover in my media library are corrected but when the title is playing, it show the name of the song and give a different album name and album cover mostly from amazon or itunes, it will not pull any covers from mp3 tags or folders.

I actually did a purge and it still did not resolve the problem

Periodically see the same thing.

Please try the following:

1) run: killall -9 cc-imaged
2) run: /usr/local/centovacast/sbin/update
3) head to your Media Library, click Options and then Purge and update library

Can I do this myself? I am just an end-user and not the administrator.
If I can do this myself, how do I start?
