Anyone know??

Any time I add a background from Cutest blog on the block, it wont let me get on my blog. I delete it and I can get back on... some of your blogs I am unable to look at as well, Mary's, Jen's, Angela's, etc. I talked to Ashley and she said she was having the same problem, not being able to look at my blog and some others. I don't know if she still is. Anyways, is it just blogs that have a background from the Cutest blog on the block? If so, does anyone know where I can go to get a cute free blog background with out it screwing up my blog?? If anyone has any answers that would be awesome, thanks!
