I would try this:
1. Close all running applications.
2. Go to Start -> Control Panel -> Add or Remove Programs or Programs in Vista.
3. Double click Articulate Studio '09 and select Reinstall.
4. When the installation completes, restart your computer.
5. Try to duplicate your issue.
***Note*** If you are prompted to locate a file during the reinstall process, you will need to perform a reinstall by following the steps below instead of Steps 3 and 4:
1. Download Studio '09 here:
