Will I need to uninstall previous versions before upgrading to a newer version?
You will need to uninstall WebWatchBot, then install the newer version .
Before you do that, you should back up your data:
If you are running Windows NT/2000/XP/2003 back-up all files and directories under: \Documents and Settings\All Users\Application Data\ExclamationSoft\WebWatchBot [3/4/5]
Your data will NOT be deleted, but it is a good idea to have a backup just in case there is a problem.
