Hi Sanal.

Have you still got your csp721_2200.exe file? If you have then install it.

Note: I have found that many upgrade to the latest SP of the Captain Sim aircraft and throw out the older ones. My advice is to back them up on a CD or DVD so you always have the older SP's  available if you find them better than the latest. I have kept all mine (maily because I hate getting rid of stuff). ;)

Hope this helps.
