Re: big problem with ms office
what makes you think its for files from the USB key? Have you tried copying them over to your desktop and then try opening them?
If the problem still exists (which is what I expect), it has nothing to do with your USB key... the file format may be based on a very old version of MS Office or come from another word processor such as Works or WordPerfect.
Try launching Word by itself and then using the File>Open menu to view the file. Sometimes this works better than double clicking the file in explorer... if it still doesn't work, you might get a more descriptive message about the problem. Also, sometimes, Insert>File option works in MS Word for files that were saved in a different format.
i think the file format is based on old version....and thats why the msg comes to install converter.
