Email indexing does not start at all

I downloaded the trial version last night. File indexing started right away, but email has not.
The message that I get on the start up is: "There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Program control panel"

I had the beta version in the past at my prior job and had no problems, but here it is not working from the start.
Any suggestions?

Thank you,
Gleb
