I am putting together a group paper for school and one of the group members sent her piece via a .docx file. My computer will not open it!!! And the bad part of this is that I cannot get ahold of her to get it any other way because she is in training for the Army right now with no access. I need to get this done by tonight and I don't want to have to buy a converter for this one thing, you know? Can anyone help???? I have Windows XP on my PC.
