Crashing upon Start

Toad Data Point & Toad Intelligence Central
1

I have one machine where Toad Data Point 4.0 crashes when I start it with the error. I’ve removed and reinstalled it twice but the error does not go away. I’m trying to get an idea on what is causing the error. The Stack Trace is

NullReferenceException

Object reference not set to an instance of an object.

Stack Trace:

Hello,

Unfortunately I’m not able to reproduce the problem. May I ask you, what database connections do you use?

You could try to solve the problem by removing the files Connections.xml and Settings.xml located in C:\Users<username>\AppData\Roaming\Quest Software\Toad Data Point 4.0.

But please be aware that you will lost your settings and database connections. You can backup the files and then import the connections from it.

Did removing these files correct the issue. From reading the error stack it seams like it should
