I am trying to open 2 powerpoint projects that were emailed to me from a finance teacher. The teacher said the powerpoints were created on a Windows PC and on powerpoint 2003, possibly 2007...i can't quite remember. When I double click to open it a zipped file appears. When I try to open the zipped file, another zip file gets downloaded. The project is saved as a .pptx.


I then opened the project on my roomates PC and then emailed it to myself and it opened, but the info on some of the slides were missing or moved around. Can anyone help me with this??
