Desktop loader unable to connect to device

I downloaded this free trial of a software that transfers and back up files. Now it prompted me to this error message which I pasted below. It is still in the step one process. I have my smart phone devices connected to my PC. Why is this error always appearing? What have I done wrong?

Connection Prompt
The desktop loader is unable to connect to the device.
You may need to enter the password on the device.
