Well, I'm a bit confused with some of the posts on this thread???
Having personally been offline for the last 2 weeks, I decided to update tonight, so, I logged into Steam, the first thing I saw was at the top of the Steam Client page asking me to verify, or, update, my e-mail address, which I did, I then went to the aforementioned email addy and waited for the message from Steam to arrive in my inbox, and verified the message, that took about 3 minutes, I then came out of my email and on my desktop had appeared a pop up box saying Game Content Conversion, Steam needs to convert the game content for Train Simulator 2013, blah blah blah blah, and then it went through the motions and converted all my content, then when it finishes you click on the box OK, and the usual pop up box appears saying your game will start in 55 minutes, or, whatever, the green bar moved across the screen and it finished, I then did a verify cache, which took over 2 hours, which I expected, no files were missing, I went offline on Steam, rebooted my system, then did a defrag and I'm safely into the game, albeit a few mind numbing hours after I started, but, completely straightforward, I can't understand all the questions asking how do I know when the game's been updated, or, how do I know if I've had the update, you sit and watch it happen after following the pop up boxes, do you need to verify your e-mail addresses before the Game Content Conversion pop up box appears, one wonders, however, I thought the whole process was boringly easy, but, my thumbs have twiddled themselves silly....
EDIT: I've just gone into my Call of Duty 3 game through Steam and the same box appeared on my desktop saying Game Content Conversion, which took about 8/9 minutes to complete and I can get into that now with no problems, does it do that with all the other individual games folks have on their Steam Account, some have over 200 games downloaded, I'd hate to have to sit through every one of them to convert, it'd drive me batty......
