if you do not have a valid backup you cannot reload the system.
I would try a RFEXI; first (this will only reset the system, not reload from disk)
if that does not work, you have 2 options:
- make cust.dat (basically print out the entire configuration) and rebuild the system from scratch
- hire someone to solve the data corruption (can't help you with that)
are you 100% sure you do not have a valid external backup? (post the printout of DUBDP; plz)
