Ae pessoal peguei esse texto num tópico de um fórum gringo, algumas pessoas respondeeram esse topico dizendo que conseguiram finalmente jogar o bendito cs 1.6 e outras não, quem sabe um pouco de ingles acho que nao custa nada tentar.
I don't know if this help, but I saw it on website:
IF YOU ARE STUCK ON "Preparing to play counter-strike" ( T H I S W O R K S - confirmed by many people)
1)Click on "Games" from the main menu
Rightclick on "Counter-Strike." Choose properties from the menu
2)Now the tricky part. Find the dropdown box where it says "Autoupdates". By default its "Do not automaticly update this game". Find and choose "Always keep this game up to date".
3)Now. Steam may crash now. I bet it will. Mine did . If it does, dont touch Steam. If its still freezed after 3 minutes. Use the CTRL-ALT-DEL-method to close steam completly and try the proccess again.
4)DO NOT PROCCED TO STEP 4 BEFORE YOU HAVE THAT THING CHECKED TO
"Always keep this game up to date". Steam will crash. Yes. Wait till' its "Unfreezed". Sometimes it doesnt "unfreeze". YES ITS GAY. Keep trying.
5)Click on "Monitor" from your main menu and check if you see some graphs there. If there is, you are probably downloading the update you need. The name says "HalfLife" first, it will change to "Counter-Strike" after a bit of time.
6)As soon as you have finished downloading the first update, double-click on "Counter-Strike" from the "Games" menu. A new, long, box should pop up with a banner at the bottom. This is the second update, and the biggest. Once it finished. You are able to play CS 1.6
Se alguem conseguir jogar depois de fazer isso, por favor nos avise!! Eu ainda nao consegui puxar e nao tem como eu testar!
