avip,
Can you please provide the exact error message that you are getting? Also, have you opened up the VI causing the error and found exactly where it is happening (which property or method)? This will help us find this error much easier because I cannot reproduce the issue.
Once the toolkit is installed and the errors are fixed, we have not had any further issues with the examples.
