As I tried to get online for the first time with 1.62 yesterday, I had the same problem, but just as I wanted to get back to Crossifre Main Menu, the global server was back again
Probably it was offline at the time you looked...or you didnt see it. If the server is online or not, you can see on the crossfire.swat-portal page If you have trouble to find the Crossfire server in the list, activate the filter option to hide servers with incompatible builds
I found that way to get on in some old treads aswell, done it, now I can see CF server also on the server list I´ve also posted it somewhere here...for other pipl who have probs with the direct login file...
