no CTD's in europe. interesting.don't upgrade directx and do something else at the same time. one thing at a time, or we'll never know the real culpritjd

JD, I think I have this nut cracked.It is none of all the things that I have described.I had to reduce my Ulitmate Traffic AI from 100% to 50% and I have no more CTDs. It seems that my PC can't handle 100% traffic in the USA and RC seems to have something to do with that, but by reducing half of the traffic, I surely lighten the burden on my PC and can enjoy the benefits of RCV4.I don't know where it is mentioned, but what is the recommended AI traffic level for using RCV4??For me, 50% AI means no more dreaded CTDs.My PC is a p4 3.2GHZ htt intel cpu, intel MB, 128 MB radeon ati 9200, 1 GB RAM etc.George

i think all of the beta testers run at 100%, i know i do.jd
