missing traffic file

Hi
After updating my N2589LMT, there was a problem.
After connecting the cable (antenna), the following information is displayed:
"A file required for traffic services is missing. Contact Garmin Product Support at www.garmin.com/support."
I checked and all my files are in place, please help.

Nuvi 2589
FV 8.50
TrafficProvider.xml ver. 4.40
It properly displays service providers but looks for a signal and does not find it.

Sorry, I do not speak English, this is an internet translator.



I made interesting observations
When entering the "Developer Info / Traffic / Traffic Receiver Dashboard" is the info "Error Freq" after entering the options and selecting "Norm" starts searching and everything works.
Unfortunately, after reconnecting the cable, the problem returns.
