Please help, I downloaded and installed iatkos 7i but once installed time machine does not show its graphical presentation i.e it actually creates back ups but it does not display the going back in time windows when you click it, it just does a screen refresh and you are back to nothing...(in a manner of speaking)

Also itunes does show album art in coverflow mode, as a matter of fact it does not show anything, just a blank black pane not even the no album folders. But other modes work great. I have since reverted back to iatkos 5i because that seems to work without a hitch. Anybody else have this problem? I have an intel 950gma graphics card
