Hi,
Thanks for the responses. I wanted to import my own decoder profile not one of the standard ones already supplied with the software and yes I followed the import procedures.
I did not update version 4.26 to 5.10, but did a fresh install in both cases. My previous version (I think) was 4.16 and I uninstalled this first, then installed 5.10. When I couldn't import my decoder profile, I uninstalled it, and then installed 4.26 and everything worked fine. So still puzzled why 5.10 would not work properly.
Regards
Roger
