yes, it was emailed to me and I have already registered it.
but previous versions that I have bought from retailers ARE in the e-store account. for example, I purchased Sonar 8 upgrade from sonar 6 from sweetwater and sonar 8's registration information IS listed in my e-store account.
so I do want to make sure that X2 is also listed in my e-store account, if for no other reason than to make sure that my next upgrade will be considered a valid upgrade and not show that I skipped X2 which would mean my next upgrade would cost more if cake thinks I don't own X2 in my account.
