[ACARS] AIRNAV 4

[Warnes, Chris]

I installed AIRNAV 4.0 today and all appears to be well as long as I dont
try using the AIRNAV ACARS decoder.

I can download data from the internet fine. I have converted My ver 3 All
Heard database OK too.

When I connect ANAD decoder ( I have ver 1.0) all seems to be well until I
come to end the connections and load grids to All heard management.
Then the system just hangs. The menu bar on the AIRNAV ACARS window greys
out and I cannot access anything. I have terminate AIRNAV with CTRL+ALT+DEL.

Any attempt to run AIRNAV again results in:
   Exception EmemTableError   -  Index iTwoCODE doesn't exist        or
   kbmMemTable3  cannot perform this op on a closed dataset.

All I can do is uninstall/install and the same process happens again.

I would be most grateful for any suggestions for resolution
