big problems with nav data

Hello guys,
I've got very big problems with my nav data since the last update 45.3. When I try to put the ICAO's into the "from/to" block at the INIT page, the MCDU says always "not in data base"! I tried to put out the Aerosoft nav data and the Navigraph in with no sucsess. What can I do? I hope you can help me!
Yours Pablo

Do anybody know how to fix this? I can't sleep when my cockpit is not working. :D
Greetings Pablo :)

Did you try the first step to rebuild the navdata by deleting the bin files in navdata folder?

For me deleting the bin files manually helpt! On the next start of the FMGS Software they were rebuild quickly and all works fine.

Thanks for your replies!
I'll try it next time :D!
Yours Pablo
