Somethings work, all cars are moving, but my insim speedo doesn't work etc. I also appear invisible to all other cars in server.
Also, skins have an error during download, eg.
SKIN : Unknown file transfer error - XXX_Arandomskin
Most likely some issues with your LFS install / Router.
Try making another clean LFS install and test and see how it goes, Restart your router / Contact your ISP as you cannot connect to LFSW to download skins.
It was working before on the same install, and I can't contatct him now... D:
Try to switch in the connection list when connected to a server pressing TCP, then it changes in UDP. It will work maybe.
Sounds like you've got some weird lag. Do a test to insim.city-driving.co.uk worth winmtr and paste the results here.
