Bug/Issue Help please!

So I purchased Starbound through Steam last night and started playing with my best friend. I go on this morning, play a little with him, exploring and fall from an extremely high ledge in one of the NPC's houses, died and the game crashed. I'm on a Mac, and single player remains fine but now whenever I join his game, it loads me randomly in the air without my ship and then I get an error message of "client-server connection no longer valid!", I've uninstalled, reinstalled, deleted all files in my Starbound folder in my "steamapps" in the Mac library as well to start completely fresh. Please help? I mean I can still play single player but not able to play with my best friend now is extremely disappointing. I'd appreciate it.

P.S. I googled and all the problems I've seen have given a log, I don't receive one, I just hit "Join Game" through Steam, and I select my character and bam, I'm playing with him. Other remedies I've seen in my deep google searching is changing your port, but again, i'm not technically joining any server, I'm just joining his game, and vice versa.
