i have no clue what the problem is... i'll log into a server then a few seconds later im right back into the multiplayer menu and there a little box at the top left corner saying "initial synchronization failed". i mean theres nothing modded or changed into the game.. the weird thing is it lets me join some severs, but it wont let me join other servers??

Do you get a message in red when it happens?

JOOS - MAIN MPSYS
OOS -CAR

Or something like that?

no..just initial synchronizatin failed at the top left corner

@Silverracer I'm having that problem. I have no idea how to correct it but I keep getting a message in red after the synchronization failure it'll say OOS-CAR or JOOS-CAR I'm not sure which. Would it have anything to do with modifying the file for the XRGT? I swapped some files to make it look like a Mustang and it worked online for some time but then when I updated the game to 6B it stopped letting me online. I've even tried using my other non modified cars and they won't work either.

In new version its added VOB mods protection (car mods) just replace modified files with original (or do a fresh install of LFS) and everything should be fine

Sorry, I don't know whats wrong.
Howerver, do you have a stable internet connection? What sort of ping do you have to the servers that gives up the error? And out of the servers that you do manage to connect - do you time out or loose connection? I'm just grasping at straws; the error might be due to a completely different issue...

@LittleBandit - As Daniel said you've got to use the original vobs (car shapes), or the connection will be refused (OOS - CAR).

You might have to use all default car vobs. Having a modded one (even if you dont drive that) might throw up the error. Not quite sure how it works.

LFS gives you that OOS (or JOOS) - CAR when either you or someone at the grid is driving a car that you have modified. If for example I've modified UF vob file and on the track there's no UF1/UFR, I'll be able to drive with other cars fine until I/someone joins with UF car.
