I really appreciate the advice that has been presented with this problem. I've been having the same problem, however, I'm using CS5 and my error code line is 171.
I've removed the .dat file and opened dreamweaver again, only to get the same error.
After deleting the .dat file, I also get the following error: "While executing selectionChanged in wa_paypal.htm a JavaScript error occured
I renamed the configuration file like suggested and deleted the extension. Downloaded it again and ran it. I'm still getting the same error codes.
Any other ideas?
All help appreciated
