Hi Jean! Sorry to hear that you are having issues with Simlink.
In addition to the instructions send by @Ian , I would like to point out a detail that I think could very well be the culprit: You are most likely using two different accounts in Simlink and Charts!
The account you are currently using to post in this forum is not the same as the one shown being signed into Simlink in your screenshot. The account in the screenshot also does not have a subscription, so it cannot possibly be the one that you used to sign into Navigraph Charts (which requires a subscription).
Please sign out of Simlink and make sure to sign in with the account that you are currently using to post here! The username in the area highlighted below should match that of your forum user.
This will more than likely get you up and running! If not, please proceed with the steps provided above!
Kind Regards,
Malte
