Why won't my left mouse button always work on minecraft?

I don't know if this helps at all, but here is some information about my computer
1) It's an HP TouchSmart Pavilion
2) Minecraft is NOT on touchscreen mode
3) My computer is basically brand new, I've had it for only over a month

The button works sometimes but I end up dying a lot because I can't kill any monsters! It really aggravates me!

Could making this game result in a lawsuit?

I was thinking of creating an mmorpg after the anime show sword art online, to do so i was thinking of basically using minecraft as the base and not having any aspect of sandbox except for buying a plot of land for a player owned house, and buying the materials from a vendor. There would be no monsters from minecraft, i would do my best to smooth out characters, and world design etc. So what i'm asking is if i can get slapped with a lawsuit for using minecrafts code as a base for this game using java. And if i claim no ownership etc to the sao (sword art online) franchise. I may not use minecraft for that i'm just thinking that would be easiest to start with as my skills with java are mediocre at best.
