obtaining unmerged data from HKL2000

when i use "no merge original index" it either does nothing or gives this error ((could not read file /,,,/,,,,//,,///,,,,/.sca header: format is not supported by HKL-2000, File could be corrupted or it may be a result of a "no merge" command))

How could this be fixed?? did somebody else managed to get the unmerged data from HKL2000 or it is problematic?

Thank you for your explanation and providing solution
