Does anyone use the latest Melodyne with X1d successfully without ANY issues?

I have plugin V2 (I think, sorry for the lack of knowledge.  Been awhile since I've updated Melodyne).
It works, but I keep getting asked to upgrade.

I am holding off because I've read multiple times that Melodyne has a memory leak issue in Sonar.  Is this still an issue?  I've read that it actually crashes X1.  This is all hearsay so I could be WAY off base, but figured I'd ask.

Thanks guys!
