Add Solution to Source Control: Nothing happens

I've had my solution with the Beta TFS 2010 in source control, but then had to setup the server new and lost my source control stuff. Now I've setup the server again with the final 开发者_运维知识库version of TFS 2010.

I cleared all my bindings, so if you do "Change Source Control" the Server Binding column is empty. If I press Bind I get an "Object reference not set to an instance of an object." error message.

I can connect to the server and I have a "Team Project" created. But if I right-click on a project or the solution and choose "Add Solution to Source Control:" nothing happens at all. No error message, nothing...

What is wrong?

Update: I created a new solution from scratch and that can be added perfectly to TFS.
