as per checking of the application, all is OK and no error is encountered, give the MDB to sir Law to check It again on his side, as per sir Law, it is still the same, the description cannot see on the application, requested to connect remotely on his PC to see the error, and as per testing with sir Law, backing up of the count encounters an error. The testing will continue tomorrow as sir Law will check if the exe used is the exe for BMS, I might give him an exe to continue the checking and testing.
