Thanks, I managed to get it installed in the end but I had to hack a bit to get it running. I basically unzipped it and copied it to the temp folder during the install and it worked. Very strange I must say ...
Now my new problem is that I cannot get the panels to show in IE 8. Look at hxxp:demo.saforeningen.no/ [nonactive], the panels show nice in FF and Opera, nothing in IE. Not sure why ...
