I am no geek either so I can give you the basic IT Speak and say "Did you reformat your hard drive to see if that solves the error?" 
Seriously, I would consider un-installing and re-installing the program to see if this resolves it. Maybe you had an upgrade pushed onto your computer and something got messed up. I just got past 3 days of IE10 problems when Microsoft pushed IE11 onto my machine. Magically, all the other problems disappeared.
