Help!

All of a sudden I can't load pictures on my blog...picasa says it's full and I have to purchase more storage. However, my storage says I'm only using 22%. I've seen a few other blogger's having the same problem.
Can't seem to contact anyone directly. Anyone know of a fix? It also says if I delete any pictures from picasa that they will disappear from my blog.

What's up with that????

Any help would be appreciated!
