security assist javascript error

I just got help with google serch issue on DW CS6, ray helped me by phone.
I now got new error with security assist 2.05.
javascript error comes up three times (same error message) when open to create security pages.
it states "AW_addMacFolderName is not defined".
I also noticed page preview and button preview stay blank in the create page window,
and when I change design setting the error comes up again, so this should be error to show the previews?
I reset the layout and cleared data cache.

attached is an updated file that should fix the problem.

locate the users configuration folder:
http://www.webassist.com/tutorials/Common-installation-issues

in the configuration folder, go to:
shared/webassist/SecurityAssist/Library

and paste the attached WA_Configuration.js file there.

make sure DW is closed when you do this, and also, delete the change file in the users configuration folder.

I can't find any attachment,
thanks

sorry, here is the attachment.

thank you.
I did that and no error appear now.
When I open Security Assist Create pages, The previews (page and button preview in the General tab and page preview in Manage page tub) don't show, instead, it says "Click Here to Preview This Page In Browser". It shows in browser when I click.
Is that noral?
Thank you.

Is preview turned of in the Preferences?

I personally find that it works better to have the preview disabled in the preferences, then click to preview when you want to see a preview than have to have auto generated all the time.

I even didn't know there is preference setting? How do I access.
It doesn't matter as long as it is functioning and creates non-error pages.
thanks

WebAssist -> Preferences. theres is ascetic for the preview.
