Hi Arturin,
Firstly, open up Simlink and make extra sure the account in which you are logged in is correct. I know you mentioned you already did this but it would be handy to know that you signed out and in again with the confirmed account.
Next, make sure that the Simlink paths are correct in environment variables. In order to check these, please refer to this post No longer connecting with MSFS - #11 by vishalahir It will guide you through the process in order to check these settings.
Finally, once you confirm both the account and those environment variables, restart your computer and check Simlink again.
Let us know how this goes,
Thanks!
