Depends on what you mean by broken. If you mean your teams disappeared, it has a button to try and rebuild them for you. If not working at all, I'm not sure.
I've been using Rematch for a long while now and really like it. It's a different interface than PBT so it takes getting used to, but is very solid and has some nice features that PBT doesn't (auto loading teams, search by ability, etc.)
