If I had this problem I would:
Open the Word Pro documents individually.
Lets take Document One
Ctrl+A will copy the contents of the file
Open Accessories - Word Pad
Ctrl + V will post the contents into the dialogue box.
Save this as File Name as Text type.
Transfer this file over to new machine with Flash USB Drive/Floppy Disk etc.
Now open the text file on the new machine & copy & paste the contents to a blank sheet in WORD.
