I had removed the old driver prior to downloading the new one. Looking at the system information screen it looks like the new one (4.12) is installed and working. I got AH to run once, it got me to the MA and then froze and I have not been able to run AH since. It starts to open the window, the window is just white inside, then a message comes up sayin the program needs to be stopped.
EDIT: That was really odd, it wouldn't run 10 minutes ago, I posted here, and now its running.
