webmatrix unable to connect to localhost:port

No idea what's happened here - I've been using Webmatrix to build a wordpress site - everything has been going nicely. Powered off the machine last night, now today am unable to run the site.

Firefox gives me this error -

Firefox can't establish a connection to the server at localhost:portnumber.

I've tried running other sites from Webmatrix, no joy. Uninstalled xampp. Windows firewall is off, Norton firewall has the appropriate exceptions.

Where has localhost gone? Anyone?

EDIT: reinstalled Webmatrix, no change. Reinstalling MySQL atm, will see if that helps. EDIT: nup. Clean install开发者_如何转开发 of Webmatrix, MySQL and wordpress makes no difference.

All seems to be working again - rebooted, swore a little, had a coffee and boom, back in business. I think it was the swearing that helped.

Thanks for the suggestions
