Yesterday, I was ready to turn off my laptop and suddenly Steam started updating. I had to go, so I clicked "Cancel" and it stopped updating like it always does. Today, I tried playing Portal and it would'nt open. I tried opening Steam and that wouldn't work, either. Finally, I uninstalled it via the Software Center and installed it once more. I tried opening Portal, and then Steam. It wouldn't work. I restarted my coputer and tried again. Still wouldn't work. Pleas help, I have a lot of games on Steam and I really don't want to lose them or my saves. Im running on 13.10. Please help!
