I can't install the update to being with. I tried downloading the torrent first and then the direct download.
I have my rF2 on c:/games/rfactor2 so I dropped the update EXE in the "update" dir. I go to launch rF2 and then to "update" but what I get is: "No remote updates found. Simulation is up to date."
incidentally, in the updates dir I still had the old update, proof that at that time it worked OK.
Had the same using the torrent version and putting it my own "Updates" folder.
I then tried the direct DL and told it to "copy and replace" the version I'd already put into my "Updates" folder...which it apparently did.
Updater then did work (well...somewhat)...because when I launch it at least does now tells me I'm running build 68, v1.040. ...
...except that all the mods I had successfully installed before now longer show up as installed. So I may have everything...but none of it is now installed or even installable, as far as I can tell.
Not sure how it helps me to go one step forward and three steps back (one for each previously installed mod) at the same time. :-/
FWIW, I've added no plugins of any sort at any point. I'm trying to keep it as dirt simple as possible here (PC is cutting edge/loaded, but running only a single GTX580--no SLI).

EDIT update: All five mods I had previously installed still show as installed in "Mod Manager."
None show as intalled trying to connect online (a serverlist that had previously showed me quite a bit of "yellow" text doesn't any more).
I will quit with it for now and wait to see what shakes out.
