I've just loaded beta7 and can't get FSX (with Accerlation) to finish starting up.The crash seems to happen when the tileproxy window displays the "Diamonds" showing (I assume) tiles that are being downloaded.Tileproxy continues to do this while FSX crashes and restarts a few times, to no avail.I have a Dell XPS 420 Quad, with 4gb of memory and Vista Ultimate with UAC off. I'm accessing the Y***O service.Any ideas?

Hmm, try the enable_hooking=off option in the proxyUser.INI file,otherwise I am out of ideas why FSX would crash for you.

Thanks that seems to have solved the problem.Great work, you're a miracle worker!
