Trying to learn the program on the day you want to use it is a recipe for disaster. There is a learning curve that I think might be pretty brutal. Unless you can find something like an old YouTube video giving instructions on the basics of the older program and work along with it.

There's a program online called https://prezi.com/ that also has a learning curve but there is a free version. It also takes some learning but they have training software of their own.
