Hi Mark,
Thanks for that, I didn't find a repair option ( I'm using FSX if that makes a difference?) so I just went with the flow and installed it, or should I say them as I also installed the ADV as well.
The two CS737-200 installation links I downloaded the other day rather than use the ones I had stored historically, so I assume that the new ones are fully up to date? Previously I had to download 1800 and 1801 links.
The sim seems to work but has many problems, which I thought had been ironed out over time.
