Uploading VS projects and Unable to locate web server error

I have VS 2003 on a XP Home computer. I have developed a website with an Access database attached for over a year without any problems. When I made some changes to the site (added a new form) it was saved to my local computer and not to the server. Whenever I try to run the debugger I get a 'VS is unable to locate a web server on this computer'. I am able to work with other websites and this is a recent change as I have not varied my practice at all. Usually I simply make the changes and then save it to upload it to the server (have never used the Copy Project function) and open the web site by clicking on the *.sln file. My FrontPage extensions were corrupted recently and had to be reloaded, could this issue be related?

 

Sorry, I wasn't clear. I am not trying to run debugging. I use CTRL-F5 (run without debugging). That's when I get the error.

 

Got it to work again. Thanks.
