Have you tried the new Microsoft adCenter

What did you think? Here's what I found.

Probably just a few bugs need worked out.

I put in 2 ad groups successfully and then couldn't add keywords to the third. When trying to login again after closing browser, it said No Such Username Exist.

I bet it will be better soon.

I am finding the same problem as well. I can't login with IE, says no such username exists. I tried in firefox, was able to login, but the get this:

The Microsoft adCenter system is undergoing maintenance

Looks like we are tsol for the time being.

Yup. I called Adcenter yesterday and they said it was under maintenance and it was working 3 hours later. Regarding the bug, a lot of this I see because the javascript is not loading properly (you'll get a javascript error on the buttom left). So usually I just go back and refresh.

very buggy. I found it difficult to figure out how to upload lists of keywords. here's what I found:

use .csv files rather than .xls
don't upload more than 3,000 keywords in a file

I suspect is will get much better.
