Thanks for replying Georg.
Steam installation was smooth and without problems, GTL version is already 1.1.0.0, no Starforce.
We didn't apply any kind of patch, just installed altbierbude autoupdater (and Python...), registered with our usernames, run autoupdater and let it download everything.
Some of us managed to open a TCP port and make it a bit quicker.
I'm still with XP, but my other buddies have Win7 and maybe some others even have Win8.
I'm the only user (admin) of my pc, without login or password at startup, and I've never had any kind of install problems.
Here's what I see when I launch GTL through Steam.
It's just the standard "Run as..." window.
It pops up even if I don't right click on gtl.exe file, I just say "Launch GT Legends" (sorry, but it's my first program I bought through the Steam platform).
"BESTIA\Ugo" is my pc's and my user names.
I unflag the "Proteggi (protect) il computer..." field and then GTL runs flawlessly.
The weird thing is that yesterday we were 4 or 5 persons, all with the same runtime problems! Lags, different cars selected...it was like our games were not in sync, but we all d/loaded the same big package.
Now I moved my GTL "altbierbude version" somewhere else (and informed the autoupdater of the new path) and reinstalled a cean GTL from Steam, at least I can play it!
I (we) keep on my HD the 20Gb packet downloaded yesterday, of course.
As you suggested, I've just relaunched the autoupdater and chose the "Commands -> Reinstallation" option. Now it's "Checking installation"...let's hope it won't take too long.
I'll keep you informed, and if others have other suggestions, please, keep them coming this way!!
Edit: after some minutes of "frozen" application, where I was thinking to kill it...

...the standard download window suddenly popped-up (unfortunately I did not capture it) saying something like:
"The following file were found:
0 Kb to download
1.500Mb
local files.
Do you want to install/download?"
I said yes, and now it's looking like this:

And now this:
Looks like there was some work left to be done! Let's hope it will fix itself.
Bye from Italy!
