@Chris > Yes, closed intentionally -- I would like anyone with those issues to please file an inquiry ticket; our rekordbox team can more readily gather your information and files (if necessary) on a one-to-one basis rather than relaying things through the forums here.
This is not a joke, I have been providing support with Pioneer DJ for 20 years, and I thank you for working with us to assist you.
I see from your ticket that Gabriel has already been in communication with the head of the rekordbox support team, and while the instructions they've given may seem rudimentary, they're covering all the bases in ensuring that your system is optimized and that's not where the troubles are coming from. Stick with it, they'll be able to fix you up.
@fabio > Same for you; please file an inquiry ticket here and our support team will gather some additional information to assist you in resolving this issue.
