How to Disable Single User Mode

I transported a package that required single user mode and it was missing a dependency and so did not turn single user mode off, now I can't log in to anything except for compiler, and that isn't turning off single user mode.

error:

Cannot connect to database 'blahblah-oneidentity.database.windows.net,1433\DB_Not_Really_My_GUID_da1337' because a system update is running.
