The cache was emptied. (I generally empty it daily.) The site looked horrible yesterday. It looks much better today. It may have been something with my PC. But, as I haven't rebooted, or done anything differently since then, I would bet they just didn't have all the kinks out before publishing. It appears to be mostly working, now. But, some of the buttons still look weird, when rolled over.
As for asthetics, the old site looked more professional. This one still looks a little on the amateur side. They probably should have just tweaked the old one, instead of a complete redesign. (IMO, of course.)
Personally, I wish they had web tools for commercial accounts. I hate having to call whenever I have a question about my account at work.
