When one of my clients tries to start Toad Data Point, he gets an error message about a NullReferenceException and Object reference not set to an instance of an object.
He is running Toad Data Point Base 4.2.1 on Windows 10 Enterprise 64-bit (10.0.17763)
As a new user, I can't upload the error log so I'll just try to copy it below. I've tried a reinstall of the program but the issue remains. The main problem is that I'm not sure what to make of the error log's stack trace. I've been out of software development so long, it doesn't make much sense to me at this point.
NullReferenceException
Object reference not set to an instance of an object.
