How do I uninstall the MySQLi extension

I purchased the new MySQLi extension, installed it and now every few minutes I get a javascript error telling me that it can't find WADUYN_CONN. Because this is annoying while I am trying to work, I installed it using the extension manager uninstall button. I then relaunched Dreamweaver opened up a page and now get a pop up window similar to the installation one but this time it is trying to go through the uninstall process. Step 1 is completed, step two causes an error that reads While executing timer, the following JavaScript error(s) occurred: At line 162 of the file "Macintosh HD: Applications :Adobe Dreamweaver CS6: Configuration: Commands: "WA_unistall2.htm": files has no properties

So I just need to know how to remove the extension so that I can get back to work.

Not sure why the uninstall script is not working.try closing Dreamweaver, then Delete the Dreamweaver Cache file from the users configuration folder:

Thanks for replying Jason. I tried deleting the cache file prior to submitting the question. Any other ideas?

recreate the users configuration folder as outlined in step 12 of the Adobe troubleshooting guide:

then uninstall and reinstall the extensions
