On the subject of MS Office downloads, I have recently discovered that you can download a free trial of MS Office 2010 - Home and Student. This contains Word, Excel and Powerpoint.
You can get the free 60 day trial by going to
http://bit.ly/office299 and following the download instructions.
Immediately before the 60 day period is up it is possible to extend the trial for a further 30 days. You can do this 5 times thereby getting a 6 months free trial. This is genuine, as promoted in last week's WebUser magazine.
When you've done this you should be able to read all the files on your memory stick.
