STEAM error (support ticket?)

Tried to install the game. Got to installing STEAM when the following message popped up.

ERROR

Steam.exe (main exception): Unable to load library Steam.dll

Been to the STEAM site - tried changing firewall options (including completely turning it off) - still no joy. Any other users got any fixes? If not, how do I get one of these 'support tickets' that i've seen mentioned?

Have you used Steam on this machine before? Do you have any other games installed through Steam currently on this machine? It could be missing the file its after/bad install of Steam. Quickest thing if you have nothing installed so far, is to uninstall/reinstall Steam and we can eradicate a bad install possibility.

Nope. First game i've installed on the computer.

Right - little update (and another question, obv.)

Now 99% sure it's to do with my connection/firewall settings on the laptop - tried to install steam on my work pc and it's fine.

So, could i just copy the STEAM folder onto a USB stick and then stick it on my laptop, or would that cause issues? ( I know next to nothing about this, as you may tell - the last PC game i had was International Cricket Captain 2005)

Converting to the USB didn't work

I am now trying to install the game via Uniloc, but again having no success (i'm getting the '-1' error message)

Have you tried contacting SEGA Customer Services yet?
