I just got a promo pro cassette and It came with the 9,10,and 11 tooth cogs in trying to take the 9 off to put in the 11. I've got the driver out and all but can't figure out the rest any help would be nice. I've been googleing for a while and can't find any info. Thanks!

Post up photos of what you have.
UNLESS the driver is a 2 piece design, I think the 9t is not removable.
Post photos.

Looks like you just need to remove the locknut on the end, slide the cog off, put on the cog you want, then tighten the locknut back on.
I think it's just regular threaded, so lefty loosey will worky.
If it's tight on there (which it probably is) you'll need a chain whip tool or something similar to remove it
