ERJ's....does anyone else have trouble getting rotation

I downloaded the new ERJs and think I did everything right. I did fly the earlier version of Grabowski's planes, and panel. Perhaps one of most enjoyable planes ever to fly (except for the reality of NO autothrottle).On the new ones, again, I can't get them to rotate...so I crash. The panel seems to be missing all the interior bitmaps, too. I miss that copilot looking at me.Any suggestions for doing this differently? Stan
