Older tracks

Hi all :)

I am searching a couple of older tracks in order to get some short 'National' track versions to work properly: A1 Ring National 2003 and Magny Cours National 2006...

I need the following tracks: 2003 A1-Ring by Marcos Togni and 2006 Magny Cours, modyfied by Bruno Gourdo...(base tracks according to info in Track Editor).

Furthermore I would like to ask if anybody has a Silverstone National track version available...???

Also if possible, do you have a working version of the short Welcom track, South Africa? I can't find the 'Welcom' folder with jams anywhere (needed according to Track Editor)..

Could someone be so helpful :>
