Well, The answer was:
1. Batery was dead ( What mounted on NC Card to keep data such as parameters, MDs , offsets, ... ) and most of data was losted
2.we need to reinstall win95 , and config Meldas magic64 NC Card as a new hardware
3. after installing autorun VB , we need to run HIM ( hiuman machine interface ) program and reload Meldas64s memory.
best regards
