Hello,
Tried the 0.6.4b yesterday. Worked perfectly.
But, when putting back the 0.6.3.7b, it worked too (still the graph problem, but speaking only of FSX in game sequence).
So all the evening, I played, but, without restarting FSX.
This morning, I tried to relaunch FSX and vLSO, and no way to get it working.
I deleted completely vLSO, reinstalled (unzipped), etc, and no way to get labels (CASE 1 in effect, etc.), audio, debrief, etc.
