upgrade problems from 6.x to 6.6
 

I tried to upgrade from an earlier version 6 to version 6.6. The interface is really sluggish and I when I try to replay shows, even at the basic mode all I get the the arrow circling. I have a Pentum D 2.8 GHZ with 2GB memory, a Hauppauge 350 and DirectX 9.0c. I reverted back to my saved directories and it is working fine again. Anyone have the same experience? Do I have something setup wrong?
