Could you clarify what you mean by AVCHD upgrade please?
What did you upgrade from and have you patched MEP17 to the latest patch.

It was a clean install with the lastest version. when i tried to inport a HD video a box pop up saying i needed to purchase the AVCHD in order to work with HD videos. So i purchase it. Then I put type in the activation code. Then I tried to import the video again. It loaded the video but no sound. I even tried to do a repair install but no luck.
