Are you sure you really bought the hoop ? I've picked things up in a store, carried them around and somehow they never got to check out....since reading the post I've realized that I can't find the manual for one of my sewing machines.....can't imagine where it could be......was using machine on my sewing table (which also accommodates another machine)......several times a day I go in search for manual....maybe it is with the missing hoop ?
