Run Time Error in PA10 and PA20

we recently have upgraded our HR system from 4.6c to ECC 5.0.i am facing a problem in my new dev client

1.In PA10 (Personnel File),when i try to display data for a pernr,i am getting an error saying that infotype 122 doesnot exist.

2.Again in Pa20,when i try to display data for a custom infotype,it leads me to short dump saying that load program does not exist.

any help in this regard wud be appreciated.

thanks
