Did word come with your computer or did you buy it separately? If it came with the computer you should be able to restore it. If separate have you lost the cd? Your sister may have a different version of word. If you tell us what make of computer and other details someone may be able to help. If all else fails you can go the the free Open Office. The 'writer' portion is compatible with word.

I had a terrible time with word 2010 and finally found a site that told me how to fix the problems. I opened a blank document in word, went to file, then options, then proofing and "auto correct while typing". I removed every check mark that area except for spelling and may have removed one or two in there. I could be typing and it would change things while I was typing, very annoying. That solved all of the problem I was having except for one and finally solved that one.

I've always made 2 documents in landscape, one for each side of the card, and used a 2 cell table to divide it. Then I just print one document, turn the paper (be careful here), and print the other document on the other side. I have no idea of how to do it any other way.

I think I solved my own problem. I went back to Microsoft Word, and pushed open. Then I can change or add.
