Should I upgrade included basic Melodyne to 4.1

I have the (upgraded to editor Melodyne 2 vers 2.1.2) and have more than enough
dongle issues without using the Sonar update to included 4 lite. Wouldn't mind
checking out new features but not at the price of going thru more
licensing hassles with my current upgraded Melodyne. Any experience out
there with this? Sometimes Melodyne gets cranky on licensing at the drop of a hat.
