I had FTX installed. After a couple of weeks, all the water around the world accept around australia disappeared. I checked an found FTX to be turned off. I uninstalled FTX and it made no difference. I still have no water accept around australia. Looks like I will have to uninstall and reinstall FSX and all associated software. I will check the FTX forums and see if there is anytbing there and keep SimV informed.
