Upon upgrading to SP 4.0 in SW2011, we have been getting this error when opening an assembly.

"The Design Table Feature was empty, so it has been removed from the tree"

Have to click "Ok" many times to continue loading. What the heck is going on. This didn't occur until upgrading to SP4.0.

Don't know what design table it is refering to or what part of any table feature is "empty"
