Well, the WOAI forums do help. I have the 2 founders helping me right now. At the moment I have Ultimate traffic 2, which is not really good. I like WOAI because it fills up my airports. UT2 doesn't. At Heathrow, there's barely any traffic. WOAI is great, and the sliders do have an effect. I have UT2 because the WOAI is not working right now on my good computer, and I had this from a while ago. Can anybody help with me though? I have an error message and it never works no matter what. help please!
