I have been using my unit for several months. Sometimes when I click on it to open it, it crashed but I clicked on it again and after a couple times it would open and I could use it fine. I am using the latest software. I have installed and reinstalled several times. I even used the previous version of the software. I am using a GTX1080 and have triple buffering set to off.
Now it won't load at all and I get the following.

Can anyone offer suggestions?

MMmmmffff....haahahahahahaha.... Sorry, couldn't resist...

Okay, now that I got that out of my system, have you contacted TIR? I had the same issue years ago using what was then the latest software.... looking at my emails, I had an issue with 5.1.3 and 4.1.038 worked for me. THIS was my forum post, but NaturalPoint Mike and I had a few email exchanges as well. I can't exactly remember how I "fixed" this problem again, but I did stcik with v.4 of the software for a while, then upgraded back to v.5 when they had a new version out.

Hope that helps!

Haha. Didn't think of that one. I tried the last version as well but no joy. I did contact Trackir but haven't heard back yet.

I had a similar issue I think and been trying to remember if it was infact TrackIR that was having issues with.. Do you have FRAPS Running?? IF so try turning that iff also try running the Track IR as Admin even if you have an admin account you are running it on..

Did you try the specific old version I used?

I had this issue once when I had an overlay running and a bad OpenGL video driver loaded...
