What receiver are you using to provide decoded data to BaseStation?

Are you aware of any recent changes, such as importing data from elsewhere or replacing the BaseStation.sqb file?

HI Anmer , I'm using PBLink via planebase . There haven't been any issues until this week .I get 2 updates per week for planebas database  and the pblink is direct to my sqb file .. and populates

Thanks.

Possibly some corrupt data in the Planebase.sqb or an updated record?

Maybe close BaseStation and rename the active sqb file.  Restarting BaseStation will create a new, empty sqb file.  Let that run or a while and see if you still get the error message?

I had a similar problem a while back. I think I had a corrupted entry when populating the SQB file. I too use Planebase. I resolved it by using an older SQB file I had saved. LIke Anmer says, rename the SQB file you are currently using and then paste in the older file and see if the error remains.
