Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
Have you already installed MYOB on the new computer?
How are you trying to import old data to the new computer?
Is it not allowing you to use a usb drive to save data and then you can restore it on the new computer
Is it the POS printer or the cash register with a 9pin D type serial connector it has.
