Game session is no longer available

[Oppai☆Daisuki]

Hello, I've been enjoying this awesome game for around 2-3 months and I recently got this problem.
I can't join any server, even the lowest ping ones because I get "Game session is no longer available". It was working perfectly yesterday and I haven't touched anything in the router or my pc. All I did today was playing Borderlands until now, then I fired up SSHD TSE and ran into this problem.

Here's the log of connecting to a serv:
