When a sensor is ready on one PC and you ready a different Sopix sensor on a second PC, the first sensor capture shuts down. This is because there is one INI file that all the sensors access in the network share of the software. When a sensor readied, it holds an exclusive lock on that file.
Update the Sopix2 extension to the newest version from the Apteryx updates page. Update the Sopix2 drivers to the newest version by contacting Acteon support at 877-422-8366. Having the most up to date extension and drivers should correct this issue.
