Actually, I noticed as soon as I unpacked my Rio that the sled and the player's case weren't made as well as my Empeg MkII was. The Rio items were not as smooth and had much sharper edges than the Empeg did and one of the hooks on the handle fouls the sled which stops the handle from folding down fully and also doesn't allow the player to lock itself into the sled. This could be your problem. I also noticed that they'd changed from Stainless Steel to what looks like plated Mild Steel for the Sled. Doesn't make it any less functional but it's not as classy.
