ERROR : Analyses suspended. Please set a valid license for the Edition you installed.Go to License p

I first downloaded sonar developper edition instead of community edition. Then I uninstall the developper to install the community edition. Yet sonar ask me a license key to start my analyse.
How can i fix this issue ?

Thx a lot.

It seems most likely that your Developer Edition is still running – have you made sure all java processes are stopped before starting your Community Edition?
