I am running windowd xp on a gateway (laptop 6mo. old), openoffice 2.3. I am taking a class at the local college and the instructor has posted a power point presentation that she did in class and I cannot open it after downloading it. She has posted one previous power point presentation that I have no trouble opening. I get a a message that says, "General input/output error" that's all. As stated before, I am still able to open the previous presentation, I cannot open this one. I did a search on the internet and came across one possible explanation. It stated that this could happen if when she posted the presentation on the website she closed the program while it was being saved. Does that sound like a possibility? I have e-mailed her with this info. hoping that she will retry posting the presentation and that it will solve the problem. However, if that is not the problem does anyone have any suggestions?
