I have the Nascar2 patch's patch available at The SimShop if you happen
to be looking for it...
http://www.racesimcentral.net/~akh/simshop.html
You must install the first version of the patch before installing the
latest patch. All are available from The Sim Shop.
It should squash some of the bugs from the first Nascar2 Patch.
Later,
Alan
