This could happen for a few reasons, but the solution will be to re authorize. Please first make sure that the version of EZdrummer that is launched in Sonar reads 1.3.3 in the bottom right corner of the interface. If it does not please update.
You will then need to re authorize. I have removed your old authorizations to allow you to do this.
