I am having the same problem using Security Assist to authenticate user.
See attached a screen shot of the error.
I have deleted the cache file several times, downloaded the latest version of DataBridge and re-installed, restarted my computer a couple of times and still dosen't work.
I'm using Dreamweaver CS6 on Windows 7 Ultimate. DataBridge version 1.1.3 installed.
How do I resolve this problem?
