New to pool mining.

I was running in a pool and I had 75 shares. I went to my room and my son decided to play a game on my computer without asking. He exited the miner and it crashed the computer as normal. I came back to the computer three hours later and nothing is running. I started mining again and now I have 15 shares.

Did I loose the original 75 shares? Does the server count them because Guiminer doesn't see them anymore.

I can start up guiminer and start mining. Every time I exit the program it locks up the computer. If I hit stop mining it locks. If I close guiminer it locks. I want to play All Points Bulletin Reloaded sometimes and I need my videocard. Maybe there is an argument I can use to give up the video card to games before hashing all the time. It's a nvidia 250.

I am not sure if you can get into trouble for mining or not. Does anyone run Tor before mining for general security purposes? Has anyone got into trouble for using Bitcoin?
