Configuration Error, out of no where!

[CHRIS]

Isn't it always the case that as soon as you post, you
solve the problem?

Apparently, adding an extra "space" to a blank line in my
web.config file solved this problem.

I would be angry that it was something stupid that like
that ended up fixing it, but Im just so glad that I can
actually get some work done now.

Maybe by changing the web.config file (by adding a blank
space???) it caused something to refresh... either way,
it's stupid.
