Designer Broken

[UGH!!]

Our developers recently upgraded to the newest version Q1 2011 2011.01.414.0. My designer is now broken. Not everyone is experiencing the same thing though. Here are the errors ... Any ideas??

System.Reflection.TargetInvocationException

Hi,

Could it be that this error is somehow related to a Visual Studio update? Do all the machines have Visual Studio 2010 SP1 applied?

Kind regards,

[UGH!!]

I originally did not have SP1, but I upgraded to see if that would resolve the issue.  I've also tried reseting my Visual Studio settings. But to answer the question ... yes - some people have SP1 installed and they are working fine.

[UGH!!]

So I think I narrowed it down.  I also have Microsoft Expression.  I updated all the Expression apps to SP1 and the errors stopped, but my designer doesn't really show me anything but a white square.  I can open the xaml in Blend and it looks great. So ... maybe I'll just use Blend a little more. :>)
