"Unable to validate.."

Recommended Posts



Just bought the MD-11X and wanted to install it right away, but there's a problem. After entering my data and hitting the "Validate" button an error message appears, saying that it's unable to validate my data.


Any suggestions?


Cheers, Wolfgang

Wolfgang, full names in the PMDG forums please.


Make sure nothing is blocking the validation, internet access is available and firewall is allowing the connection.


Validation issues are usually best handled directly with PMDG Product Support rather than the user forum, try here:
