Hi.
This error usually means the host PC where IME is installed is interferring with the IME processes and causing them to fail. some common things to check:
1- make sure the PC doesn't have a software firewall running that can cause IME interprocess connections to fail.
2- try re-installing the software as it could be damaged by some other software.
3- make sure communication between IME and the sensor isn't blocked by some device on the path.
4- try a different PC.
5- try to connect to the sensor while you are on the same LAN as the sensor (to rule out some layer 3 device on the path is interferring).
Regards,
Fadi.
