PC Join via Steam isn't working (kinda)

[TimeyMarey007]

I searched for other threads like this. There were, but none were matching the problem I have.
The one I have is actually more of a Steam-related problem than anything.

When I click Join via Steam, the box appearing asking you which friend you want to invite doesn't appear for me. Due to that, I can't invite, but others can invite.
Any solutions?

NVM I didn't realize what Join via Steam actually was. It's for joining a friend's game, not hosting a server. That's what Host and Play is.

Lock this thread, please.
