I have Quickbooks POS V11 (2013) Multi Store Edition. We've expanded and I've added two registers. I now have my old register as my server and two client workstations. When I go and install Quickbooks POS on the client stations and chose client workstation, or single, I chose client. I put my original product ID in, because the multi-store ID won't work for this part (I upgraded from basic to Multi store previously). Now the server is running multi store and the other two registers are running basic. It won't allow me to enter the upgraded product number in anywhere. Can anyone help??
