(message sent to Sony Customer support but I'm still waiting for a response)

In spite of a reinstall of both Vegas 5.0b build 160 and Microsoft's Framework 1.1.4322 as well as an install of DVDA 2.0a build 121, any time I try to run ANY script (for example "BatchRender.js"), I get the following message:

An error occurred during execution of the script
F:Program FilesSonyVegas 5.0ScriptMenu\BatchRender.js

Exception thrown by method called.

The "Details" box says:
Failed to create managed object: 'Sony.Vegas.ScriptHost'

Any ideas? I'd sure like scripting capabilities again. Thanks.
