Only one worker running

I just downloaded the trial because I was looking for a client that supports multi part transfers. However, when I configure it for such, (I enabled multi part, put 10 workers/part and put 10 workers in the queue) it says "Working... (1 of 10 workers running)"
 
Is there some sort of configuration I'm missing to make it work? I'm using SFTP and I haven't changed any of the default settings. Using 6.0.2168.0

The number of multi part transfers is not reflected by the number of workers. You can double click the file in the transfer queue and you will see all the connections in the log window.

Thanks, but shouldn't all my designated workers be running?

It depends on how many files are in the queue. If there is only 1 file in the queue, only 1 worker is needed. If there are 10 files ore more, 10 workers should be running.
