Corel Wordperfect Suite 8 Professional

I can not get it to save my work, and I do not know why, I have used other word perfects before.

Package arrived on time, new in original box with discs, manuals, etc.

I have had problems using this product, probably my fault. But I keep getting messages that I am not allowed to do certain things and really do not understand this. The book that came with the product does not address the problem I am having.
