dudes with steam install problem:
open up Run (if using Vista/7 type run into the searchbar and it'll turn up)
Then type " "C:\Program Files\Steam\steam.exe" -install D:"
Probably don't need to have the first set of "s around steam.exe but better safe than sorry
Replace D: with the drive your disc is in.
Should start installing from disc rather than downloading 2x8gbs lol.
