What error or message are you getting when you try to go to Photobucket.com?
Their "help" site, which is actually just a bunch of answers to common problems and not very helpful, is here:
http://pic.pbsrc.com/help/PhotobucketHelp.htmNot sure if you'll find what you're looking for there, but it's a place to start. But the error may not be on their end, it might be on yours, so do try to explain what's happening in as much detail as possible.
