As a temp solution, make all list server entries 'jazz.nimrod-online.com'
And use the Lastest JazzForce (1.0c i think?) the one that supports nimrod-online.

At the moment, the american list server has buggered up and is therefore stopping both list servers sync'ing with eachother. At the present moment jazz.nimrod-online.com is getting about 95% of the active games / game requests, so for the time being its recommended you use it.

Hope this helps.
