In an ASP.Net web app that's been working fine for months I just added a simple button and in the click event a routine to update a record in the database.  When I went to browse to the app in IE I got this.  It was just working before that.  I commented out the button click event code block and I still get the error.  What could have happened?  Another page in the same app still works fine.

[Edit] I take it back about the page that was working.  I chaned the text of a label and saved the page and now it gives me the same error.  Could it have someting to do with the company firing the Network Analyst/Administrator on Thursday?

[Edit] In a completely different web form, as a test, I changed one character of text on the page and save it and now that page is giving the same error.
