Dave,
I recently switched from PFE to PF3 and am very happy with the new features and the greater realism than in the old version. There is one issue:
Using the hotkey "Say Again" I can hear "me" requesting "Say Again" but I never get an answer from ATC. I tried all three option (default - ATC log - both) but no success. Also the ATC communication log opens but is empty.
I tried it this night after a flight and this morning at the beginning of a flight - both zips with the logs are attached.
My system: PF3 3.10 with FS9.1 on WIN XP 64 bit
Thanks for your help and all the best
Thomas
