Hi!
I am having a similar problem here.
I tried to do, i followed step by step of RiggsFolly Wrote about.
It fixed a little, but not everything.
How so...
Now when I go to wampserver -> Localhost
It open's the menu in the browser, so I clik on Project1 in the My Project list.
HE WORKS! GREAT! Before it didn't.
BUT! When I go to wampserver -> My Project -> Project1.
He goes to WampServer Localhot page.
