Kalarm install problem and “is configured multiple times” error

I installed kalarm and got some errors, quoted below, and kalarm said it was unable to create the first alarm. Now “New” alarm is grayed out as well as some other options. Tried resetting to defaults and also removing and reinstalling but no change.

Errors installing kalarm:
