Just wondering if anyone can help? I have been using a trial version of office 2007 on my laptop which runs windows 7 and have saved documents on a flash drive but when I try to open them on an older machine running windows xp in office xp they are invisible so therefore I can't open them - any ideas how to solve this? Wondering if I should just uninstall the trial version of office 2007 and install office xp but maybe this is impossible on Windows 7 - ahhhh! Why are things so complicated! Thanks for any help!
