Probably didn't explain too well. So this is the route I took.
Ran the repair utility to see if that fixed the problem, it didn't, so uninstalled reinstalled, it didn't fix it either.
I am using the default 737-700 profile and BEFORE connecting to FSX tried to set a different voice set for Captain and Co-Pilot, but on testing no voice sound was heard.
FDC is connecting to FSX no problem and I have checked the black box login and it shows the date as 23/07/04 with a few issues which can't be relevant to my problem because of the date.
Where is the FDC/logs folder? I have done a search but can,t find it.
My system is Windows 7 64bit quad core.
Hope this makes it a little clearer.
