steps taken this time.
1 - Open teeworld
2 - Erase host address:
3 - Click on "Reset Filter"
(this basically puts a x next to "campatible Version" and "standard gametype"
4 - Click on "Refresh"

under the internet tab I just see "no servers found"

What do you have written under "host Address"?
I also notice that under the "demos" tab after I hit refresh that there is nothing showing either :-(

could you give me a step by step of what you do and whats ticked etc?
