Can't 'repair' or upgrade CC app

My CC app appears to be stuck and won't update (see screengrab). When I try uninstall/reinstall, it recommends 'repair'  but that doesn't help.  When I try to uninstall my one current app (Audition) to allow for CC uninstall or repair,  the process stalls in Waiting mode. 

I just subscribed to the All Apps package,  so need to fix this.

Thanks.
