DobotStudio Pro 2.6.0 does not save my Blockly program

#1

I am making my first steps with the MG400 in DobotStudio Pro.
An annoying problem is that when I save my work I receive the message:
‘Failed the project. It has been backed up locally. Please check the network and try again.’
or
‘Tips
read failed’
When I try several times to save it finally tells me that the project is:
‘saved succesfully’
but when I close Blockly and try to open my newly created program it tells my:
‘No file found. The file does not exist’
The good news is that I can find the file as Backup project in Blockly .
Any clue?

I noticed that DobotStudioPro stores the Blockly programs in:
AppData/Roaming/BlocklyProjectBackup.
This location may have very slow access.
Can I change this file location to a local directory?
