I am using Dreamweaver MX

I installed an Exension and when I try to run it I get the following message

JavaScript error while loading Hlooper2: Unable to open script file “…/HideRegionClass.js”(error2)

Do you know what this means?

:d:

I have installed other extensions and they are fine. It seems that the last two I installed give a similar message. Is it possible that they weren’t built for MX?
