used tweak and after that i cant join Public drift server....(didnt connect to server)

what to do ...:S

Did you get CPW? When you join a server that doesnt allow tweak, you get CPW and get banned for 12 hours. If you want to join an untweaked server, dont only turn off the tweak, restart LFS too.

Using tweaked LFS you can only join tweaked servers safely. Joining regular servers may result in a CPW ban depending on tweak used. Enough of those and you may be banned for a longer duration from entire LFS (one month i think), if those count towards regular ban accumulation. Be careful.

What I would do in your place would be to download fresh LFS, install to another place and copy over those settings i wish to have from tweaked version. Such as setups, skins, screen resolution etc., but not the tweak eh. This way you keep the tweaked version and the regular one which would be better then messing with single version, then removing/adding tweaks

If you want to race in the community, clean install, have fun.

If you want to use tweak, then join only private servers that run whatever tweak their running, and have fun.

Is that simple enough ?
