Updates to the TimeToStart software are periodically released by Split Infinity Music. The program can check for updates on the Split Infinity Music web site. Click the "Update?" button on the settings display. After asking your permission, the program will check the web site for the most recent version, and if it is newer than the version you are running, the response web page will provide you with a link to download the most recent version.
Minor upgrades (such as 1.0.23 to 1.0.25, or anything less than a full version upgrade like 1.x to 2.x) will not require that TimeToStart be unlocked again. However, if you upgrade from 1.x to 2.x, you will need to purchase the upgrade and use a new unlock code.
When you update, the program may rebuild certain preferences when you first run the upgraded version, to make sure that no outdated settings or incorrect information remains in the TimeToStart area of the Windows registry.
