I get a pop-up with this error message every time I open my program:
Failed to load dataset because of the following error: Object reference not set to an >instance of an object
Every time I try to compile I get errors saying my typed TableAdapter and TableRows don't exist.
When I double click on the data .xsd file to go to the designer view for the dataset I get an error screen with that repeats the Object reference bit and gives me this call stack:

This program has been working for a while and it just started doing this today. Today I witched the .Net version and then changed it back and altered the installer, but I don't know why any of that would cause this issue. Need some help on this. I'm on a really tight time schedule.
