I have just installed WLM 8.5 but all the tabs on the left of my contact list have gone...and the space button (the one you use to go to your own space) at the top on the main window has gone too.
And when i try to check someone's profile by right clicking on their name, it doesn't do anything. And you can't go to your contacts' space either from there, cause "space" isn't there.

Anyone else having the same problem?

The tabs can be restored in Messenger's options, in a place that's really obvious.

Yes i do know that, and that's the first thing i did. The tabs aren't there, there's an empty column.
