Yes, the troubleshooting thread is written also for you ...
If you need to uninstall and reinstall Liquid to correct a problem, I suggest you do it this way:
From the XP Control Panel Add/Remove, remove Liquid components in the following order:
1. HFX for Edition
2. TitleDeko RT
3. Liquid
Now run your registry cleaner a few times to make sure your registry is as clean as possible. Reboot your system and then reinstall Liquid. You may have to reset your render drive in Liquid's System Settings and your media location in Media Management so you might want to make note of those before starting.
