Transmit interlock on 60 meters after updating to newest version

I have been using my 6500 on 60 meters for years. All of a sudden I cannot transmit and the window pops up saying transmit interlock has prevented me from transmitting. This has never happened before and was not happening right after I updated. It just started this morning during a QSO. Went from OK to no transmit due to interlock. Any ideas out there?

    Is your high cut greater than 2700?

    It maybe because something in the setup has the possibility of transmitting out of band.

    Maybe the location region is not setup for your region and frequency permitted.

    Maybe the RTTY shift is out of band edge.

    I am having the same problem since V2.10.1. Band width is OK, Always happens after using remote. I play around and get it fixed, the same solution does not work the second time.
