None of our programs modify or change anything related Simconnect, it's not even possible to do that from a Simconnect client application. If your TrackIR is not connecting to FSX, it's entirely unrelated to any of our products.
Do you have other FSX modules, like FSUIPC for example ? They are all dependent from Simconnect so, if the problem was caused by our software altering Simconnect in some way, ALL other Simconnect modules should be affected in the same way.
