: Always copy and paste your codes. Characters like 0 (zero) and O (letter) or 1 (one) and l (lowercase L) are easily confused.

The JRiver upgrade system is incredibly generous. You can use a valid Registration Code from —even the older Media Jukebox 8.0—to qualify for an upgrade discount. Moreover, if you own a license for a single OS, you can upgrade to a Master License for a small fee. For example, when upgrading to a new version, adding Master License support often costs just $8 more than the single-OS upgrade.

JRiver’s licensing policy is generous for households. A single platform license allows you to install the software on multiple computers that you personally own within your home. You do not need to buy a separate "exclusive" key for your laptop, desktop, and home theater PC. Master Licenses vs. Single-Platform Licenses

: Existing users receive a significantly cheaper upgrade price when a new major version is released.

JRiver releases a new major version of Media Center annually. If you already own an older version, you do not need to pay full price. JRiver offers massive "Early Bird" upgrade discounts (often up to 50% off) when a new version enters beta testing. 3. Multi-Computer Friendly Policy
