can't view PDFs - get a blue loading bar

[anon]

Hi. I'm having trouble viewing PDF's. They used to work after I clicked a placeholder. Now embedded PDFs cause a popup saying "there is a problem with , but now I get a blue loading bar on a gray oval with a pure black background. I can't right click anywhere on the page and if I click the "temporarily allow all this page" button on my toolbar it grays out but will not load. I think I updated Acrobat Reader and that started the problem. Anybody know how to fix this?
