Working with AppleWorks from Tiger to Snow Leopard

Hi, When I upgraded my iMac from Leopard to Snow Leopard, I found that I could not open old files from AppleWorks. ( I know AppleWorks is old software BUT it is what I had used from day one).
When my HP Printer drivers weren't available, I reverted to my laptop using Tiger. Now I can use my HP Printer with Snow Leopard, the AppleWorks items I transferred to Snow Leopard. I cannot open up the AppleWorks files. I receive a window which reads "The file was not found". Has anyone had the same problems?
