Is anybody else having problem installing the trial verison of this?

I'm running Widows XP, Vegas 8b. I ran the installation and a message that LooksDX.DLL had been registed appeared - clicked Ok to acknowledge then the installer hung and I had to end the process manually. Tried it again and this time the installer finished successfully (still got the DLL mesage). But when I tried to use it in Vegas I got a message about not being able to display a preview window. Uninstalled, tried again and now back to to the original problem of installer not finishing.

Thanx

Ian
