SB4 not connecting to voice room server (I think)

[learn-by-flying 37]

I have just switched back to FS9, and I am trying to get SB to connect to VATSIM. I had this problem with FSX and forgot how I fixed it. When I load FS9 I get the sim ready to go with an A/C at the gate and then start SB4 from outside of FS. I go to connect and everything works as planned until I set a frequency and the green lights near the comm 1 and comm 2 box do not turn on. On the bottom of the SB window it says I have voice/text on 118.10, I can read and send text over the frequency and can see other aircraft. Heres what I have done so far: -Turned UPnP off-6809 UDP forwarded to my static IP of the FS9 machine-23457 Both TCP/UDP forwarded-3290 Both forwarded-3782 Both forwarded-Mic setup in both SB and MS messenger with restarts-Ensured sound card and mic drivers are up to date. I am about to pull my hair out. Any help greatly appreciated. Tom

Edit. Fixed, switched network cards and it seems to work now, not really sure how that helped? Tom
