So, if I remove printer and connect ASDL to COM, reconnect printer? Do this work for me?

When I enable spy mode, a blue screen of death appeared. I had to reboot a few times. But I still get the same message.

After I can open soft, I see message "Starting the program" and no more works.
Although I changed the printer's configuration to let COM be free and then started the software.

I am using the trial Advance Serial Data Logger.
I have a thermal printer using serial port and normally work.

When I install ASDL success and I configuration Serial Port, I see message "COM3 is closed."
Can you give me how to configuration or what must I do.

Thanks for your help.
