Answer 1

You need to re-install the program, your's has been compromised by either to many things running while your playing or you have a "worm virus" these virus's take awhile, but they slow down your computer and they start eating away at your programs,I had one and it took awhile to notice but I had to save my info and buy a new motherboard, hope this isn't your problem,just re-install the chess program, but delete your old first.
