Yes, I know I'm a bit late with this, but the server is back up and running for Sven Coop 5.0.
Although I updated the server to 5.0 back when it was released, the server plugins refused to work and I felt I couldn't get the server running until they were updated. And I'm glad to say they have been for the most part.
As always, any bugs you may encounter just let me know.
Gmod 13 has been released, and as expected, there many bugs that need to be worked out.
With the many changes made to Gmod including the workshop, I have installed the server fresh and will be installing addons as they are updated. All adv dupes are saved and will be copied back once all everything gets worked out.
