There's more to Jan Kees's problem that that, Mike. If it was as simple as just sending another activation, it would be done already.
As far as I can tell, the problem is that the software sees itself as already activated, but that thirtieth repaint has "broken" that activation. Therefore, it currently cannot be reactivated. It needs the code to be fixed so it doesn't fail when you add too many repaints, not a (comparatively) simple reactivation.
