If you purchased a license for an earlier version of Cloudgarden's JSAPI implementation, or have lost your registration code, you may enter in the email address you used to purchase the license, and your registration code will be emailed to that address.

Once you have your registration code, you may use it in the LicenseManager tool (part of the TalkingJava SDK) to validate your license.

Note that the personal license allows you to validate your license on up to three machines, provided that you abide by the license terms (ie, you are the sole user of those machines).
