Infrastructure Map 2012 project redirection will not work.

[NorthernMAP]

Hello all.

We have a simple asp redirect project that has worked for MGE2010 and MGE2011 but when we change our web.config and default.aspx to the new Infrastructure Map Server 2012 we get everything back but the map.

(I mean everything but the map because you can use the custom searches to query out a property and the attributes are displayed in the properties tab and the map zooms in but there is no map, Custom Header comes in, Layout is visible, right click menu works, coordinates work in the bottom left hand corner ect)

An error is thrown when you click in the blank space where the map shoudl be and says "Invalid stream header exception."

How can I fix this?

Thank you
