Make sure your old Nokia Developer account is properly linked to your current Nokia account. First you need to make sure you can login to your Nokia account.

To be safe: go to https://sso.developer.nokia.com/logi...4290-268008791 and introduce login & password. If you are not sure or find any problems then click "Forgot your password?" and proceed. Also if unsure, create a new Nokia account.

Once you are properly logged in: do you still have problems?
