I figured out how to add some teams. When manually entering teams, it can sometimes get into a weird state.
I do have disk writing privileges, and I'm running the application as administrator.
If you try to create a team without a "Short Name" or a "Nick Name", it will show you its read/write error message, and enter a weird state. After adding one of these teams, you cannot add any more teams and it will tell you the team already exists, even if the team number has not been used before. Then, it randomly had an unhandled exception after I tried a few more times.
It also seemed to enter this state after adding more than ten teams, even though they all had all their information filled out. It's worth noting that some of the downloaded teams, which work properly, do not have all the information filled out.
If you use this address for both of the team download URL's, you'll get a bunch of teams to play with, but you have to wait a few minutes for them to download.

This is kind of unrelated, but how do teams update their robot name on this list? Some teams seem to have their most recent robot names on the list, but we have our original 1999 robot name there.
