Let CCC completely overwrite X3e install - seems fine (w/Braintree)
Welp...the forums finally convinced me to bite the bullet and where I had only installed the tutorials and the Anderton items plus the core SPlat program from CCC originally, I let it install everything again...so all "green" lights, so to speak.
I'm not concerned with filling my C/OS drive, as it's 1TB, and 2TB drives for my audio and samples respectively. But I understand the concerns of those with smaller SSD. I guess you could move that content and point the program paths differently (?), but I'm not bothering at this point.
That said, I did NOT re-install Melodyne since I have the upgrade, nor Dim Pro or Rapture. But the rest yes.
Maybe a thread of this type of info might be of some use.
