Hi, I need help. I normally use version 5.xx of abb's cmt 1000 software to configure the avr unitrol 1000-15. Out of necessity I had to install version 4.xx of the software coexisting with the previous one. When I run version 5.xx of the software again, I get the problem in the photo, making it impossible to connect to the AVR. Version 4.xx of the software also shows that problem. Is there a solution?
