Object reference error appeared when saving a map in Visual Trader 4
I am new to Visual Trader and I have been attempting to setup user data in Visual Trader 4. I could create a new map and then I edited the symbol list and transferred the symbols. When I click on save, I get the ‘Object reference not set to an instance of an object’ error shown in the screen capture below. After closing and reopening Visual Trader, I get another error ‘No data exist for row columns occurred’. Then the VT4 screen opens up and I get the ‘Object reference not set’ as before. And now, when I click file, I cannot open it. What is wrong with the procedure I followed? Can you please help me to fix this issue? Thanking you for helping me out.
