The error that you encounter suggests that your system in not properly configured and you can't run the application yet. To fix this behavior, it's advised to check again if you properly connected the device to your PC. Also, make sure to check if you didn't set up a low or high value for the baud rate. The optimal value can be find in the device's spreadsheet. I suggest that you access the Help menu from the main interface of the application. There, you will find any related information that you can use to set up the program.
