General rule of thumb

Dont buy any games for windows live for MP (except for DOW II , DOW II is a bit retraded in sense that it uses steam for DRM and windows live for matchmaking , which means you'll find people to play with , Dirt 2 , Street Fighter IV cause SF IV you'll find somebody). I dont recommend buying a Games for Windows Live for MP. Look at great games like GTA IV , LCS , James Bond 007 QoS

blame gfwl

i think my flatout cant mp also, it say some region cant play mp, meh got it for rm7 so dun care 

I got Flatout UC and Dirt2.. come play with me..haha

connection no problem with me... kaakakaka..

I got Grid but only play offline
Only played online once but always didn't finish the race (against bulubulu lol!)
So I shy away from Grid online...

You bought the game already V3nz?
Let's vroom vroom then

Edi does it , but if you want somebody just to help you once then contact me . I am not doing as sales but if you want some minor help just once then yes. Else go get from edison83 or deimos or those who offer the services

Bought Flatout Ultimate Carnage and Red Faction Guerilla out of spite.

bcoz Grid is not on Daily Sales..

U buy now 66%. Tommorow daily sales is 90%... you feel like crying later.. probably you still dun understand the mechanic of Steam sales.
It has Daily Sales and whole week sales. lolz

lolol 2mb only... d/ling now

Download from the link on Deimos signature.

Download and unzip. Open the folder and double-click steam.exe. Let the new Steam update itself. Once it has updated fully and you can login, copy all the files in that folder and paste them into your current Steam folder. Replace everything. Then delete the unzipped folder and start Steam the way you normally do. For best results try it when everyone is asleep. Good reason to wake up and watch the match later. 

i restart my modem and computer and it works for me.

solve for me. why don give it a try?

All those who cant login and update, click my username and search for my posts for the solution to your problem. Lazy to repost again and again lol.

But at least your Steam client is now updated. Sometimes it's like that, you still wont be able to login. I get that like every day since the sales started. Keep trying and you'll eventually get in. Sometimes it will prompt for your password even though you've ticked 'save my password'. And don't delete your clientregistry.blob file.
