I recently bought my woman the hl series pack off of steam. I've bought her games on steam previously, and she has been using it for quite some time with no issue. However, right about the point in time that I bought her the hl stuff, her steam has been screwing up something awful. It began benignly enough with just saying that she couldn't install some games due to the steam servers being busy (which a little insistance worked through). But now the games are actually on there, certain ones say that "the game is currently unavailable". Not only this, but some games she already had and that had been working fine for months have started coming up with the same error. Oddly, it seems to only affect games with multiplayer... HL, HL:OP4, TFC, HL2:DM, TF2 and L4D come up with the error, yet HL:BS, HL2, HL2:EP1 and HL2:EP2 work as per usual. (Her Assassin's Creed Brotherhood works, but that may be because it runs more off of Ubisoft than Steam.)
At times while Steam is running, it also seems to lose connection (that's what it says), yet games seem to continue downloading. At the same time she seems to lose connection to her friends list too, saying that no-one is online. Also the last time we tried logging her in, three or so of her friends had simply disappeared from her list.
Any suggestions? Steam's being a real bitch on this one.
