I have made a habit of periodically uninstalling TTD and installing a new copy if I start to have issues.

I have never really had a crash as you guys are describing, however, my IR pro stopped working recently and it was not until I unistalled and reinstalled (2x) that I got it back on line.

It was giving me the message, "unable to load capture component" and did not show the enable capture button that usually appears when you first fire up the IR library manager. I exchanged my IR pro after reinstalling but the new one had the same issue. I reinstalled a second time and that did it.
