incredible, its very difficuld to know now whats happening there, all will be easier if a special patch existen for that(im working on that)...
If you cannot connect into a LAN or UBI server than it seems like that your FarCry don't have connection to the WWW.
Can fix it:
1. Try to launch your FarCry as Administrador!
2. Try to launch your FarCry in Compatibility Mode(Windows XP Service Pack 3)
2. or try Point 1 and 2 in the same time!
