Following a power failure the computer running xplane was assigned a new ip address as a result when I load xplane with RXP GTN750 enabled I get an error message telling me that the ip address RXP is using does not have a NIC assigned. I seem to remember that during installation I was given the opportunity to enter my ip address in a text file used by RXP. I cannot locate that file or find another way to change the address RXP is looking for. I have tried reinstalling and have not been given that opportunity again. My ISP makes it very difficult to use static IP so I may need to do this every now and then.
