Hi!
I just installed Engine 2.0 in my PC and i would like to start from scratch and use a clean library, but the previous playlists/crates are being recognized.
How can i delete all the previous playlists and the previous information and create a system folder from scratch?
Thanks!

I would uninstall E.P.
- rename engine folders inside music folder to engine.old
- if you have other local drivers (like d:) rename engine folder on the root to engine.old
- reinstall E.P.

Unless of course youve got an internal ssd in your prime, because the library on there is locked and you cant just delete or rename it.
This is the problem I’m facing having just gone from 2.0 back to 1.6.
