Yikes! El Octa and the 231B stand arrived but they refuse to mate!
It looks like the stand is missing a critical piece but the included instructions don't illustrate what pieces are supposed to be included, nor does the MA website, so I'm not certain.
In the attached photo circled in red is a plastic fastener which holds the stud in place. There is a hole on the opposite side of the stand to accomodate a second such fastener (where the red arrow is pointing), but it appears to be missing? Since there is only one fastener on one side, when I attempt to tighten the stud, rather than standing upright, it begins to look like a leaning tower of piza (see photo) and is too unstable for me to attach the strobe to it.
I'm going to contact the manufacturer tomorrow but thought since a few of you have the same stand you might be able to confirm that a second fastener is indeed required, or point me in the right direction if i'm just embarrasingly badly bungling this whole thing... 
thank you so much again for your help
