Itunes wont show my songs in album just shows blank colored thing??

I have a mac (Mac Mini, Mac OS X Server Lion 10.7.5 (11G63)) and I have itunes updated and everything else that I would think need to be updated but this has been happening for so long. For all my albums I can not see the songs, like it just wont show them when I click on album cover / thing. But my music does show when I go to songs. It also wontshow in, Artist, and Gernes. 😟

Heres an example of what it does:

Thank you in advance!!

I've asked this problem before and someone suggested it was a grouping problem but that didnt really answer it because I cant even see the songs in the albums to begin with, just a blocked colored thing.
