default client is not configured correct
Please clarify: When do you get the error?
- Do you get it when you click CONTACT US from menu?
- Or once you are on the contact page and try to send and email?
Usually getting an error trying to load an email program from a website is due to not assigning a DEFAULT browser and email program.
Open your Internet Explorer. Tools > Internet Options > Programs tab Check to see if your email program is assigned in that page. (if you use Outlook, assign Outlook, etc). You may need to make that browser your default.
BUT you are using VISTA so you will have DIFFERENT issues. This is not a web issue. Purely Vista this time.
Looks like others have run into it too!
I found a tutorial for your VISTA Mailto link situation here.Good Luck!
