Sodick 812 help

Hi, got an old 812 mark IX Sodick that we bought recently and it has been going well. Yesterday we went to run a program but keep getting the error "this T code is unavailable error" I'm not sure why as the program has always worked and when we go back to some other programs that previously worked they also suffer the same error.
I think I remember it referring to T83 T89 T97

Also can someone help with the hole location centre program, I can do it manually with a convoluted process but I believe the 0145 program on disk should do it but I can't get it to work.

Thanks in advance.
