lol it's so easy to do, just go to
www.proracingsim.com, go to the support page and download the dynoSIM program they have, install it. go to
www.astalavista.box.sk, search for dyno, and download the crack there (i only tested the crack that isn't from EMINATOR). even though they're different version, the program works fine for me. just copy the dyno2003.exe into the dynosim directory, and use that exe instead of dynosim.exe
