[Cura not playing nicely]

I have always used Cura and it has always performed without a hitch........until today.

When i try to import an stl file the program just shuts down! I have tried an uninstall and clean install but the problem persists.

Very frustrating.

Does anyone have any thoughts or come across the same problem?

 

Thanks in advance

[Cura tree supports]

Are any future changes being considered for this feature,

eg....more than 1 wall (option) / infill for stength and reliability?
