Hi I've recently taken out and dusted down my old TrackIR2, which has been gathering dust for many a long year. Much longer than I thought actually to the point of it now being obsolete!! Damn I spent a lot of money on that thing back in the day!! Anyways. A friend reminded about these forums & I remembered I used to post here, well back in the days I suppose when TrackIR2 was cutting tech!! I need version (4.1.028 ) if anyone has them? i'd appreciate any help. cheers.
