This page concerns the retired Crate Hackers 3.9 generation. Its menus and troubleshooting steps do not describe the current app.
Use the current setup guide
Start with the current Crate Hackers guide and use the official download page.
Before changing a working older setup
Back up your music, DJ library and any data you need from the old app. Avoid a major migration immediately before a gig. If you are unsure how to preserve an older workflow, contact support before uninstalling or deleting anything.
What to send support
Include “Crate Hackers 3.9,” your operating system, what you need to recover or continue using, and the exact error. Do not follow old database-deletion or reset steps for a newer version.
