Is there a way to roll back to a previous version once updated? I did install Aeria Lite and then I noticed an update to 6.7.1 of Kontakt which I did. but since then, Kontakt crash every time. Did a full uninstall/reinstall, same thing. Uninstalled all Native Instrument softwares, including Native Access, cleaned the Native Instrument folder in My Documents, still the same after a fresh reinstall. I have 172 Gb of free space on the disk, so that's not the issue. The web site only point to Native Access. Not sure what else to try at this point. Can't seem to find a way to roll back to 6.7.0 in Native Access. The crash logs are unreadable, so I'm at the point I'll have to open a case with NI, but I wanted to see if I could roll back first. Anyone succeeded to do a rollback with Native Access (or another way) in the past? As a reference, I had Kontakt 5 installed as well and this one was still working (I removed it since as part of my troubleshooting steps to clean everything NI), so it's really something related to Kontakt 6. Now, whether the issue is caused by the update to 6.7.1 or the installation of Aeria Lite, your guess is as good as mine, but I don't see why it would crash after a library install. However, following a software update, that would make more sense, hence the reason why I try to roll back. If anyone has any idea before I reach out to NI. My studio is completely down at this point...
