I have tried all versions, Preview 50 has no download link, Preview 74 is still invalid, it is in my game but it does not work properly, for example, the tachometer is empty but the like area where the speed numbers should be and there is not rpm bar, and the tachometer is not moving at all, it_s like A picture, so please share preview 50, or is there any other way to solve it? PS: In the video, you see that your system is in Chinese. Do you have instructions in Chinese? My English is not good. It looks very laborious.
