I am getting an error while launching Toad Data Point. It keeps on crashing anytime I try to open it. The error says: "Toad encountered a serious error and must be closed. Please save your data and close the application. We apologize for the inconvenience".
The log error says:
---------------------------------------------
NullReferenceException
Object reference not set to an instance of an object.

I fixed it by removing the connections.xml file kept at "C:\Users<USERNAME>\AppData\Roaming\Quest Software\Toad Data Point 5.4" It is loading now properly with no issue
