Topic: Problems w/ TiltViewer & CS4

I'm trying to evaluate TiltViewer but I keep getting the following message:

Error: General Photoshop error occurred. This functionality may not be available in this version of Photoshop. - Could not complete the ScriptingSuppot command because of a program error.

I'm running the 32-bit version of Photoshop CS4. This problem also happens w/ SimpleViewer, etc.

Any suggestions? :(
