You should all have this version. Also I should have a newer edition up next week.

Are you running anything else other than Compu Live you that computer?
An Audio program maybe, a video program, something else that may have an interface connected to it?
If you are not running any other programs, then uninstall the version your currently have.. delete the SL2002 folder in your C:drive, then reinstall it.
Install in regular mode, not beginner mode. There may be something in the Beginner mode causing this, but I haven't heard any of this yet.
