After building a new pc and installing rfactor, it is not possible to connect to the server. Twice reinstalled rfactor, still the same error.
You most likely have a mod or skinpak that wants to use an older version of the Porsche. An update from S397 that changes a version number often is the cause. Either delete any downloaded skins or mods or check the download site for an updated version of any custom Porsche skins.
I have, before reinstalling the pc it worked, everything is purchased. and does it on all modss and tracks
the vTCC stuff indicates a skin or league mod that is based on an older version of the Porsche. Find it and unsubscribe/uninstall if not a steam subscription. Probably not a bad idea to contact the creator and and let him know it needs updating as well.
