Before the start of class, I had such a minor inconvenience. I couldn't start my prepared presentation. I have a new power point on my computer, where the pptx extension is, but at school the computers will only open the older ppt extension. Here I learned in the past that if I don't know the environment, I save everything in both formats to avoid complications.
