OK, thanks for the help. Tomorrow I'm going back to my LBS and getting my money back, I'm ditching them for good
(spent 2 months instead of 3 days waiting for the adapter, each time they said it'd arrive in 3-4 days or next week or tomorrow... well, 2 months later the WRONG one arrives. Not the first time they've done this, I'm done with them, I've put far too much trust into them)
