I need help with my kitchen aid ice cream maker attachment.

I can't swim. I can neither sing nor dance. I don't own a digital camera or any camera for that matter because I can't take decent photos even if my life depended on it. I'm no good at public speaking.

Knowing that I can't do any of the above mentioned stuffs don't bother me that much. What bothers me is that I can't attach the kitchen aid ice cream maker (model KICAOWH) that my uncle gave me (whoops! i meant us) to my 5 qt artisan mixer (model 5KSM150).

I can't attach the drive assembly to my mixer because of a small circular metal piece located just below the motor head and right above the area where we attach the dough hook and balloon whisk and the paddle/beater (whatever it's called).


According to Kitchenaid, the ice cream maker attachment can fit any stand mixer model. Any stand mixer except mine?????
I tried sending an email to Kitchenaid's customer service center but I can't access their website!!! Arghhhh!!!!

I don't want my dreams of making delicious, homemade ice cream melt away....
Okay now that line was cheesy!
Seriously though, I need your help beautiful people with kitchen aid mixers and ice cream maker attachments.
