I have a hunch I'm missing something obvious, but I've finished making a flow, set as start location, saved it to make sure there were no warnings, then clicked "run" and I get:



Insufficient Privileges

You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary. 

Anyone have any ideas as to what I'm doing wrong?

*Note:  I'm using the cloud Flow Designer. I use a mac, so I can't even try the locally run version
