I've recently downloaded office 2013 and when I try to load up saved word and excel files it shuts down and says that its encountered a problem. I've installed it several times and its the same problem.

I could load it up and create new files but now I cant even do that. I have got office 2013 on my notebook and that works fine (word crashes every so often but not so often now).

Could someone explain what the problem is and how it can be solved.
