So, I have just gotten the trial for TF2, but as I opened it, it got stuck on the loading screen, with the medic, spy, and heavy. It does not finish loading. I also have this problem with Portal: The first slice, but not with the hl2 demo. Anyone else have this problem? Anyone know what's wrong? Please don't tell me to just buy the full versions, I already plan on doing that after finals this week.
