Thanks all for your feedback and ideas. I seemed to have fixed it in a roundabout way which I may have to revert as the game crashed when I was switching views between objects. First I tried to use the Super Tomcat Pack to replace the A and A+....that did not work. When I copied the ODS orgininals back in, overwriting the Super Pack Cats, it started working....now, just then I spotted something that I missed in the installation instructions, I did not use the optional SF2NA files to use the stock Tomcat data. So I did that too.
It all looked like everything was solved, apart from the crash. Not sure if ODS is prone to occasional crashes?
I may try to do a clean setup again. BTW I also added the latest Viper Team F16's as I felt that the included F16's were dated. To check, is there an official way to add more up to date aircraft to ODS, like the F16's for example.
Thanks,
G
