Updated to unity 4, now can't get my serial numer correct

I updated to unity 4, and also saved my serial numer and made a screenshot of it. Now when I want to enter my serial number in unity4, it says it couldn’t find it. What can I do? I have an android and ios license.:frowning:

Did you upgrade your serial to 4.0?

You can’t access 4.0 with a 3.5 serial unless the 3.5 serial has been upgraded.
