Unity 3 - DirectoryNotFoundException - Web Player Building

Hey guys, really frustrating problem!

Ive had this problem and fixed it, then it stopped working again. Im really unsure what Im doing wrong.

I goto “build” and set the active platform to Web Player, then it asks me to select a folder.

I select a folder, hit build, and constantly get this error:

Error building Player: DirectoryNotFoundException: Directory ‘zzz\Projects\iBots\builds\WebPlayer’ not found.
UnityEditor.HostView:OnGUI()

I end up with a html file and an image, with no Unity 3d file in that directory.

Anyone?

Bump, serious problem.
