I don't get any further than testing to get on with just the default paints in the Cheetah, haven't tried to add the Vettes yet or Clif's skin...the server works fine with the Jag, AD_Daytona, and Cobra_Hardtop, when I add just the Cheetah without Clif's paint I get Checksum...
My conclusion there's something wrong with the Cheetah.
I deleted all the Vettes and Cheetah from both the server and my PC before downloading the field and putting them back in both places.
I am now going to test the Vettes. without adding Mick or Trae's skins
