The reserved error implies that you are trying to access the analog input channels on the device while another analog input task is running
With multiplexed data acquisition boards (E-Series and M-Series), only one analog input and one analog output task can be run at the same time. This is the case because all analog input channels require use of the same channel multiplexer and sample clock. Thus, in order to perform multiple channel acquisition, all channels must be included in the same task.
