AI Traffic download

Hi,
Anyone knows where I can get the AI traffic download. I used to have it on my previous laptop, basically air traffic in any world region showed local airlines at airports and also ATC called the real airlines. For example flying in DFW I could see/hear DL and UAL flights. In Prague CSA e.t.c. The planes also looked in particular airlines color schemes. I do not seem to be able to find this download anymore?
Thanks
