There are a couple of ways to go:
1. If you have broadband- download the trial version of Wordperfect Office from the Corel site- and convert the file to Word (178 mg)
2. Download a program from one of the internet download sites that will let you convert the Wordperfect file to HTML format. You can them open the HTML file in Word.
I spent time searching the internet for a program that will convert WP to Word but there doesn't seem to be one.
