Wrong Documentation
After reviewing your "Common Installation Issues" document I deleted the WinFileCache.dat file a couple of times along with uninstalling and reinstalling SecurityAssist several times.
What I kept seeing in Dreamweaver each time I reinstalled the extension looked nothing like the descriptions in the "Getting Started Guide."
I finally discovered that the documentation "Getting Started with SecurityAssist" I downloaded when I purchased SecurityAssist as part of the Dynamic Suite is for a different version of SecurityAssist. The Getting Stated Guide is for SecurityAssist 1.1.6 and the version I just purchased is 2.03
On the SecurityAssist webpage securityassist/
under the heading "How Tos" there is a link titled "How to apply Register/Login functionality to your checkout page.
Clicking on that link takes you to this page registration_on_checkout.php
that describes how to apply the register/login to the checkout process.
At the top of the instructions is a note about eCart and SecurityAssist along with links to "Getting Started Guides" for each application. The link for "SecurityAssist Getting Started Guide" takes you to this page
securityassist_gsg.pdf
which is the documentation for the old application (v1.1.6 or higher) which unfortunately is what I downloaded thinking I was getting the instructions I needed.
You could eliminate a lot of users' headaches (literally) if you'd place the new documentation in that final link.
Thanks,
Robert
