The current pre-release of the client ("pioneer" in the version) is only compatible to itself. So you can only play with other testers. Please be aware!

Okay, so I moved my supcom to a SSD drive
You "moved" it? Like, by hand? Copy-paste?
I would try uninstalling and reinstalling. Even now that it's already moved. Probably something didn't move or didn't get moved properly.
