Make sure you set the Default kernel and the Notebooks kernel (in 
Evaluation menu) to "Local".

I get this message when the notebook's kernel is not defined in Kernel 
Configuration Options.  The notebook you have trouble with might have a 
default kernel name different from "Local".

For example, create a new kernel setting in the kernel config. options 
dialog, name it "abc", set the notebook's kernel to "abc", save the 
notebook, delete "abc", reopen the notebook, evaluate something, and 
you'll get the same error message.
