Okay, deleting a category is a bit tricky. Please do the following.
1.Locate TDP Application Data directory - go to Help -> About and click ‘Application Data directory’ link.
In the folder that opens make a backup copy of Connections.xml file.
Open Connections.xml file in Notepad.
Search for the name of the category you want to delete. Let’s say it’s ‘Development’ category.
If this category was defined then you’ll find ONE OR MORE occurrences of the string like this:
You have to delete ALL such strings. You do have several occurrences if several connections are assigned to Development category.
- Save Connections.xml, start TDP and make sure all your connections are present.
