Blank Page

Got WordPress uploaded to my host (laughingSquid) this AM. I’ve been going through themes on the WordPress themes page and uploading them. I upload them and check them out, then go back and find more.

Lat upload (all via FTP) I go back to my dashboard themes page and I get a blank page. Now every page in my dashboard is blank.

I’ve refreshed Firefox and tried it in Safari, no luck.

Any ideas? Could something have corrupted something somewhere?

thanks
