I tweaked my LFS a bit, and then removed the tweaked power, or, etc. But some online servers that are not allowing tweaks, are still not letting me join, though i completly removed my tweaks.
someone help please

Oh, now I can join, after adding RIMS forder to my LFS. sorry for bothering you, admins.

I think you have to close lfs. Then try again

Mentioning of tweaks is not allowed on this forum.

Make a backup of all files you want to keep. (setups, screenshots, replays,..)
Then delete and re-install LFS.
Simplest way, nobody knows what files you have altered etc.
