I've posted on the trackIR forums, as well, and have confirmed with them that the newer versions of the trackIR software do work fine, but that the most up to date version for my hardware (version 4.2) does not work. As I said, it seems that it might be something with BattleEye blocking the software from initializing.

Thank you for the response.

Since the updated .55 stable branch version, I have noticed that the Battle Eye window shows that it is blocking the trackIR version 4.xx software.

Changed reproducibility to "sometimes" from "always" because I was able to get it to work correctly a few times, but it keeps switching back and forth between working and not working.
