Tried to access a Query’s execution plan and ran into a wall.
The error is pasted below.
An error occurred while executing batch. Error message is: Error processing execution plan results. The error message is: There is an error in XML document (1, 5093).
Looked more into it.
And, determined that I was using SQL Server Management Studio v2005.
In this case I should be using a newer version, v2014 to be exact.
