CSS Menu Writer 2.01 Installation Problems

I tried to upgrade to 2.01 by first removing my former version of CSSMenuwriter - the system kept telling me that files were in use and to close Dreamweaver. I closed DWCS3 and rebooted my machine - still the same problem. So I tried disabling and removing through Extension Manager with DWCS3 closed - more error messages. Then I tried to install the newer version without removing the old version - more error messages. Now the problem is compounded because I tried to remove/upgrade the Google Pro Maps but got more error messages such as:

"The following translators were not loaded due to errors:
The following Javascript errors occurred:
Unable to open script file "C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS3\Configuration\Shared\WebAssist\GoogleMapsPro\Library\WA_Configuation.js" (error 3)

and

"While executing onLoad in CSSMenuWriter.htm, the following Javascript error(s) occurred:
In file ""CSSMenuwriter"": Reference Eror: on Startup is not defined

Obviously something has been corrupted but I can't install or remove either of these new extensions and am continually getting error messages while working with DWCS3 when I'm not even trying to utilize a WebAssist Extension.

When I try to remove or disable either of these 2 extensions, Extension Manager just hangs.

Oh yeah, using Vista 64 Pro (I know...I know...)

Any suggestions on how I can remove the old versions of these 2 extensions and install the new ones?
