I currently run Vista Home Premium (64 Bit). And I dont when it happened, but I have no sound for my Logos at all. It doesnt play the "start up" theme and I even tried the "read aloud" feature with no sucess. I made no changes to the program settings so I dont know why I am having problems.All other sounds play on my computer except for my Logos. Should I uninstall the reinstall Logos? Can anyone help?
