I'm completely unable to use squawkbox anymore, so I am stuck to the FS2002 ATC. Mt problem is that I can't get clearance unless it's VFR. I ask for IFR clearance (yes flight plan filed and eveything), but get absolutely no response, and am still able to send the message. I can keep sending the message all I want, but I'd never get a resonse out of it, and during this, other aircraft are calling in and getting clearance just fine (IFR as well). Anyone have any ideas? Already uninstalled, cleaned, and reinstalled, and that didn't help.
Thanks in advance!
