When I try to run the PC Pitstop OverDrive utility, I get an error saying the utility failed to load. I am running Win7 with IE11. I have followed all troubleshooting steps on the link provded in the error message. I tried running IE as administrator with no luck. I have used the ActiveX test utility and it works. When I run OverDrive, I never get a prompt for a certificate. Any suggestions would be greatly appreciated!
