Everything worked great. I was using office 2003. Then a PC tech
recommended that I use CCleaner to get rid of all my old, unnecessary
files. I should not have done that! that's when the trouble started.
So, Yes, outside of office, everything plays, runs etc using Windows media
player.. Here is what I have done up till now to try to fix things.
I got office 2007 -- that did not fix anything.
I uninstalled & reinstalled Windows Media player 11
I uninstalled and reinstalled All-in-one codec
I uninstalled office 2003 & then had to reinstall the dictionary for it
because Office 2007 only comes with a French dictionary!
That's where I am now.
