Accessing the Pro Site account page after changing the name

Hello,

By Default in Pro Sites a user can access their account information by going here: https://automotivewebsource.com/pro-site/. However, that link no longer works because I changed the Pro Site label in settings to "Automotive Web Source" without knowing that it would change the URL.

So now the only way to access that account page is here: https://automotivewebsource.com/automotive-web-source/

I have change the label in Pro Site setting back to "Pro Site" but the original URL still gives me a 404 error. How to I get it back to https://automotivewebsource.com/pro-site/ working?

Thanks,
Chris
