has anyone tried this extension in dw8

Hello,
The extension requires Dreamweaver CS4+ as it is described in the requirements section:
www.dmxzone.com/go/21622/sliding-paypal-shopping-cart#requirements

I bought it anyway so when we upgrade to cs5.5 we will have it.. It almost works with DW8, the only place it fails is when you try and set up the tag. It also is impossible to remove.. I had to restore my computer to get all the errors out of dw once I uninstalled the extension
