hm, dont know what bug this can be, just try it a few times, perhaps it works^^

steam doesnt really make big problems at my pc (win2k)

you should reinstall steam at first. if this doesnt work, do it as alien said. start steam, wait a bit. if nothing happens, "kill" steam with ctrl+alt+del. start again, wait a bit... if this doesnt work, deinstall steam, download it again from steampowered.com, install again, try again.. can't be that it just doesnt work o.O

I've downloaded it llike 50 (not lying) and reinstalled it like a million times. It just doesnt work

wow, now i get an error message when trying to start steam... yay ._.

I have found out how to fix the problem. Don't want to say this put '"thank you Valve '
the way you fix it is by Deleting the ClientRegistry.blob file in your steam directory and then restart your computer and then just download a little update and it will work.

And that is it[

when you started it, did jst nothing happen, or did you get an error message? I get one, and if you got it, too, then i'll try what you said..

yea i got a error message. Just do what isaid in the above

i've just reinstalled it again, and steam itself works fine again... but now when playing battlegrounds over steam there are many graphics errors... damnit
