Hi Lyn
Give Prochem a call, explain what happened and they will hopefully have a solution. If you've rubbed it in it may now be a dye stain and might leave a permanant mark.
try also a heavy pre-spray, (enzyme pre-spray,?) agitate (don't scrub!) leave for 5-15mins and then extract with machine.
Prochem are on 0208 974 1515
Hope i've been of some help
Regards
Martin
