I am a bit frustrated, which is probably mostly my fault. Our church has a Mac that runs the presentation each week. A friend installed Proclaim on my PC at home, so I do not know what my password is, if any, and my friend is on a mission trip so I can't even ask him how everything was installed. What I am trying to do is prepare the presentation at home (on my Windows PC), save it online and then use it at the church (on the Mac). I assume this is possible. If so, how do I do this?
