OneDrive Business (MAC OS X) Crashes

Since installing  OneDrive for business on my Mac it's running 90% of CPU power constantly. 

I have tried restarting my MacBook Pro.  Once restarted, I get a pop up message "problem occurred with accessing the Office Document Cache. Do you want to Repair this problem?” If answered Yes, this open the Microsoft Upload Center. Have emptied the Office Document Cache using the Upload Center preferences numerous time and this does not resolve the problem.  

I have to manually Quit OneDrive for Business from the Menu Bar.  

I use:

Mac OS X 10.10.2 (Yosemite), current on all software updates.
