TeamBuilder Not Working....Again

Was excited once the bug preventing TeamBuilder teams being downloaded was fixed.

I started working on some custom teams and then all of a sudden the site quit working again. I can edit and preview previously created teams, but every time I try to create a new team, I get the following alert:

"Error: [400]: An unexpected error occured during this operation."

This only pops up when I hit Create a Team. I tried working around it by hitting Create another Team from the submit screen, but to no avail.
