I really appreciate the advice.
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 as suggested in another tread and deleted the extension. Downloaded it again and ran it. I'm still getting the same error codes.
I also get another error code
at line 171 of file "c:\program files\adobe dreamweaver CS4\configuration\floaters\wa_paypal.js": retStr.match\has no properties
Any other ideas?
All help appreciated
