I am unable to Autoplay the DVD of Digit September & October to view the contents. I was not having this problem before September 2006. I can explore it to view the folders & its contents in Windows Explorer. When I click for Autoplay, I get an error message saying "Digit.exe is not a valid Win32 application" I din't find any virous when I scanned with Quick Heal My System: Win XP - Ver-2002 - SP2, AMD Athlon 64 Processor 3000+, 1.80 GHz, 256 MB of RAM Antivirous: Quick Heal - updated daily for definitions. I request help & guidance to correct this problem.
