Hi Michael, I'm using IE8, I did the reset and my firewall and virus programs were turned off but I'm still getting the jscript error. My computer came with an OEM version of XP so I don't have an installation disk and can't reload XP. The data files come from an airfoil database and don't come in a 3DM format so I guess I'm hooped.

Thanks for all your effort!
