On line flying.

I've been getting online with FS2004 .Flying with Vatsim using Squawkbox 2.3,SBrelay to patch SB to FS2004,Servinfo and Roger Wilco.When connected via SB,the "ATC Directory"in SB fails to show the available frequencies.Connection can be made by looking up the RW server on Servinfo,and writing it into the IP address box on RW then clicking join.Can anyone tell me if it is possible to get SB to do this - as it does in FS2002.Or is it because SB2.3 is not really made for 2004 and we'll have to wait until SB 3 becomes available?Dave
