Charts not working with avitab

When I try to link my avitaband navigraph sccount I get an error that says “AviTab Error: Invalid RS256 signature”

My charts were working fine but out of nowhere I have 0 charts available for all airports. Any help would be great.

Same issue here. Was mid-flight and noticed it had stopped working, same error code

Please see Can't Login From Within X-Plane and Avitab

I suggest downloading and reinstalling latest Avitab.

Cheers
Ian
