Hi Alex,
It looks like we don't have your organization in the system to associate your support portal account with. This is why you see "NO ACCOUNT ASSOCIATION" at the top right corner of the portal when logged in.
Please see this article for more information and how to resolve it: https://extremeportal.force.com/ExtrArticleDetail?n=000014472
It will be helpful if you can provide the portal team with a few of your device serial numbers so we can try to locate your account.
