Cannot get Local to add new sites

I really like using Local. I am running Windows 7 and have it installed with 2 sites currently running.

However, I cannot add a new site. I always turn off the firewall beforehand, but once it begins adding a new site, it will get to the site folders area and go round and round and round. Eventually I may get an error msg, but if I have 2 sites there already what’s the problem?
