Hi freeze,
I want to add that I completely agree with Richard about OpenOffice and give it a strong recommendation. I know people who have Microsoft Office and downloaded OpenOffice and ended up using the OpenOffice equivalent program by choice (despite the fact that it's free and they had paid for Microsoft Office). The only downside is that it does not contain equivalent programs for everything in Microsoft Office (e.g., there's no equivalent for Outlook), but other than that one, it covers most that are typically used most frequently.
Since it's free, at least download it and give it a try. You can compare it to the Office Trial since you now have that working. If you decide you'd rather have and pay for Office, you can always uninstall OpenOffice. If not, then you'll have a great suite of products and you won't have spent a dime getting it (and can instead uninstall the Microsoft Office trial).
Good luck!
