How to open Corel .qpw files? Cannot open those files using Quattpro8

Hi,

I need to open some QPW files. My understanding, these files were created using Corel QuattPro software. I have installed Corel Wordperfect suite 8(on Win XP) which has Quattropro 8. But, I cannot open those QPW files using QPro8. Getting error - "Cannot open file ...."

When I am creating a new file using Quattpro8, it is creating a file with extension -wb3. So, I need either find out how to open those qpw files using Quattropro software or a different  software that opens qpw files.

Any help/suggestions would be highly appreciated.

Thanks
