Cannot use -ja or -clone with more than one client at a time

I have tried using either of these but I can't get more than one client to work on the same session:

ghost32.exe -ja=autoz -sure –ib -rb 

ghost32.exe -clone,mode=restore,src=@MCautoz,dst=1 -sure -rb

Whenever I do more than one client using either method listed, I can see them in the connect window but if I hit start it just doesn't progress. If I connect one client using either command it works fine.
