Having a ton of issues with Lightroom v 3.3

Lightroom will freeze in the middle of my work and I cant make any edits so I have to force quit, and then force quitting will cause my edits to be reverted. 
Or, if I close the program and come back to it later the photos in my album that I deleted will reappear and the edits will be reverted on the ones I wanted to save.
Up until this week, I only had the issue with Lightroom freezing which wasn't a big deal to me to force quit and then restart because all of my changes would be saved, the other issues appeared within the past couple days.
