Hello. I hope someone can help me. So here's the deal. I've been using Office X for some time. I bought Office 2004 for Mac (Student Teacher Edition) from a friend who upgraded last May. I got the manual and the Product ID with it. I never got around to Installing it, but my hard drive failed recently and Apple replaced it, obviously without any of my stuff on it. So I decided if I have to reinstall all my software, I'd go ahead and use the Office 2004 as I don't think the Office X is fully compatible with Tiger (because of it's age and a few issues I've had with it over the past two years). Now, here's the problem. When I tried to install it, the product ID didn't work as the Product/CD Key. I called my friend and she no longer has the box or the Product Key, and of course, the Product key from my Office X doesn't work. So now I'm stuck. Is anyone familiar with Office 2004 for Mac? Is there any difference between the "retail" version and the Student/teacher version that would prevent the Product Key from one with working with the other? Would anyone be willing to share their Product key with me, to install the software so I can get back to work? I've already lost 4 days in time (and have to recreate 2 days worth of work that was done after my last file backup) and don't have time to deal with this stuff. Thank you in advance for any suggestions/help.
