Thank you for the report....
My code works for your report also.... wanted to make sure you were not using the legacy XML driver.
Only thing I can think of as to the cause is something is broken on your PC.
Check your references and make sure they are all version 13.x.x.x. sometimes VS doesn't update them all. Check your app.config file and make sure you have this in it:
<startup useLegacyV2RuntimeActivationPolicy="true">
