analog output error using MCC USB-1408fs

I receive the following error when starting an analog output using a MCC USB-1408fs
MCC: Count must be integer multiple of packet size for Continuous mode
Any suggestions as to what is going on?
The mfile is:
SampFreq = 20; % Hz
Duration = 5; % sec
NSamples = SampFreq*Duration+1;
t = [0:1:NSamples-1]'/SampFreq;
v = 1+sin(2*pi*t/Duration);
ao = analogoutput('mcc',0);
addchannel(ao,0);
set(ao,'SampleRate',SampFreq);
set(ao,'TriggerType','Immediate');
putdata(ao, v);
start(ao);
wait(ao,Duration+2);
stop(ao)
delete(ao)
clear ao
The error is generated by the start(ao) command.
Other information:
MCC Instacal v6.01; matlab 7.4.0 (R2007a); data acq toolbox v2.10; winXP
