Simply, if you want to do some racing now, use 0.6B (the latest stable patch) rather than the test patch, unless you want to test the test patch. There aren’t many people in the servers using the test patch either. And when the new official version is out, you will be asked to automatically download the update when you show the list of hosts in multiplayer.
I've merged your thread with this one, as you asked the same question as someone had done here before.
Basically, you just need to put the original 0.6B LFS.exe file back into your LFS folder. You can download it from here. Then you can have separate exe files for 0.6B and 0.6B8 or whatever.
could someone reupload the normal 0.6B exe? Sobis' doen't work anymore, and the 130MB download just to get that one .exe would take quite long on this line here.
strange, now your link works again Sobis, was "no connection to server" when I posted that post. But I had problems connecting to my own dropbox at the same time, so maybe it was a problem on their side.
