try plugging in without the bateries...Also check your adaptor as well as your ac requirements on your keyboard..It specifically calls for a Casio AD-5 Adaptor.

PC drivers available at Casio

If you have a MAC google casio driver for Macs by 3rd party.

Here is the manual for it http://casioelectronickeyboard.danielcadams.com/cs44-p-stand-cs44p-casio-electronic-keyboard-user-manual/

Just add some adhesive Velcro (hook and loop fastener) The industrial rated for 25 pound should be good for most players, 75 pound rated minimum for Jerry Lee Lewis type players.

Set the stand at the height you want, put the hook tape on the stand leg top and then target the fuzzy strip to the piano. Be aware the pound rating is rated per square inch- so you will want to put a 10 or 12 inch strip of fuzzy on the piano, and 1 or 2 inch strips on the stand leg.

The link i have attached is a direct to Casio's website and their user manuals. i dont think the one your looking for is on the however, you might find a model very similar to yours to use as a reference.
is there a problem your having with the keyboard?

It sounds like the sustain is stuck on as if a sustain pedal is active. You don't mention if you have one, however if you MIGHT have one and you have used a Roland pedal, that brand is reverse sensed and would cause note to remain on.

Unless the stand was specifically made for the Casio, the holes probably will not line up with anything. You can COUNT on them being Metric threaded and you have to be careful to not put too long screws in the holes. If you stand doen't line up with the holes, best to secure a piece of plywood to your stand first that is drilled to match the synth and attach the synth to the plywood. I don't know how your stand is made so I can't give you more details.

Try uninstalling and reinstalling both the keyboard and the game. If that doesn't work then the keyboard may not be compatible with the software.
