This happens a lot when people use registry cleaners. EMC10 uses a particular registry key to store activation and registration information, and this key is very prone to being broken by almost any registry cleaner. When that happens, the whole suite is immediately disabled.
The fix at the moment is to do an uninstall/reinstall, or use the Roxio repairer utility.
Prevention is to either tell your registry cleaner to leave the Roxio key alone, or not to use a registry cleaner.
If you locate and export that key before your software is disabled, then you can re-enable the suite by importing the key again after the calamity. The value of the key is system-dependent, so it can’t be used on another system.
