After install 10.6 epson scanner 4490 wont work

Hi, I recently installed 10.6.8 on my Santa Rosa macbook ( is was running 10.5) now my Epson 4490 scanner will not open the scanner software, such as "digital Ice", ect. I have reloaded the software from the Epson DVD and still have no luck? It worked fine with Leopard installed....
