Logic Pro and WaveBurner Pro require you to attach a USB device, called an XSKey, to your computer to use the applications. The XSKey is programmed to know if you're authorized to run a particular version of the software. However, sometimes the contents of its built-in memory may get inadvertently changed, leaving you unable to use the software.
The XSKey Updater, an easy-to-use tool that can analyze your XSKey, can correct these issues in most cases. Please note that if your XSKey is physically or electronically damaged, the XSKey Updater will not work.
