ASI120MM PHD

I've always used PHD Guiding ASI120MM And with great satisfaction.

I recently bought a new pc with windows 8, PHD now hangs.

just installed the drivers, but the new work is no longer restart, the screen remains black and the PHD crashes. Using a ASI120MM as a guide.

I also tried the backwards compatibility win xp, the first time it works, and the second, black screen. there are solutions?

Thank you Mario

Hi Mario
