Downloading File Manifest Screen




I just got a new laptop for Christmas with Windows 8 on it and installed CoX. I used a disk. Whenever I open the program, it asks me if I'd like to allow the file to be modified. I say yes. However, instead of downloading the patch, it will flash "downloading patch" for a second, then switch to "downloading file manifest" and "Fixing: cityofheroes.exe" and remain on this screen. I've gone into the firewall and allowed the program, but I'm still stuck. Can anyone provide me with a solution to my problem so I can start playing again?

Addendum: Specifically, I've noticed that trying to fix "cityofheroes.exe" gets stuck at 6.5M each time. Has anyone else experienced this and found a solution around it?
