If you have purchased an Unlock Code for DART Software and it has reverted to lock mode (ie trial or demo mode) the software needs a new, fresh unlock code. You can always get a new Unlock Code from this page.

If your email address or zip code has changed since you purchased the Unlock Code or since you last re-registered the software, go to this page first to Re-Register. This is required if you try to use your current email and zip code addresses and they have changed.

This unlock system only works with the latest versions of the DART Software. o download the latest version of the software, go to our "Software Updates" Page.
