Just to clarify once again - I have made some screen capture(s) - to show the error messages
Here is the ORDER of the error messages
1. Cant read calibration - this is the FIRST error message
when you dismiss this message - by clicking the OK button you then get the 2nd message
2. Cant read user calibration - message
when you dismiss this message - by clicking the OK button you then get the 3rd message
3. Cant start sunsdr2dx - message
when you dismiss this message - by clicking the OK button you then get the 4th message
4. Cant connect to sunsdr2dx - message
Hope the above screenshots - give a little more clarity to the problem at hand!
Thank you
