Help my GPS shows no info!!!

[akka]

I install the new AIRAC database for my PMDG 747 but after that, all the Garmins (the old fs9GPS and Garmin 530) suddenly lost all data info. It shows up but there is no route info waypoints etc. It shows the active route only but no airpots etc. Anybody knows what had happened and how to restore?

Thx a lot
