Hey.. i have half life 2 installed and an account with steam.. everytime i try to launch half life 2 it says its decoding the files and stays on 20% for as long as i would let it.. or if it doesnt do that it says preparing to launch halflife 2 and then stops responding... since i have dial up, would it be possible to go to someones house who has dsl, download steam, log in and then update what ever needs to be updatesd?
