My system is Windows XP and I feel my computer user level is just basic. I have lost all the history in my Microsoft Works(7.0) Word Processor. (no clue how it got lost)When I go to My Documents I can see all the files from history but I cannot open any of them. When I try to open a file it directs me to buy Word Perfect(R) 11 software with an upgrade to Word Perfect 12 for $99.00. Should I buy the software? Is there a way to move the files back into the Word Processor history? Next to each file in My Documents it says WPEntrust Signed Document.
