getting an error with NivoSlider install in DW (CS4); works fine in cs6

while executing onLoad in dmxNivoSlider10_install.htm, the following javascript error(s) occured:

In file "dmxNivoslider_10_install"
initUI is not defined.

I'm dead in the water. The extension shows it being installed in Adobe Ext mgr, but starting dw I get this error and I can't do an Insert of the nivoslider. It does show in the menu, but nothing happens.

Hello,

Please clear your dreamweaver cache: www.dmxzone.com/go/16740/clearing-dreamweaver-s-cache/ and install the extension again.
