NCAA 14 by EA Spors...freezing issues with Ultimate Team games

Does anybody know why EA Sports can't fix the glitch with the ultimate team game?  I truly enjoyed playing ultimate team and was completely hooked...I bought packs and spent a bit of money...then the game just started saying loading when I would do a solo challenge.  Does anybody know how to fix this?  I know EA has probably dissolved the division...but it would be nice for them to fix this issue for those of us who were deticated to the franchise!
