Thanks guys. I guess that's what I really wanted to know, if Violet could do that easily, associate my bunny with my serial number.
My bunny isn't getting any messages I send, or that anyone else sends me, but it sure is getting SOME sort of messages, because she says random things at random times, and the radio works. I can also ask her for the weather, and dutifully she'll tell me it's snowing (which it's not. Where ever the previous owner was, it snows a lot though.)
So I know she's communicating on some level. And when I used a public OpenNab server to test her, she worked fine when I sent the SN a command. So I'm assuming it's a messed up SN on Violet's database.
I did register a few accounts, which I told Violet about in my help ticket, because I was having issues and someone told me it might help (of course, it didn't). I don't know if it's a problem either, but when I was trying to register her, I had a computer glitch in the middle, and ended up not completing the registration, so I entered the SN in twice on the same username. I don't think that would mess it up, since it still would have been associated with my username, but maybe it did.
So I guess I'll sit tight till Violet gets in touch with me. Hopefully they'll be able to put her right Monday.
I sort of hate to return her to ThinkGeek and wait another week or so for a new bunny, when she seems to work okay and it's something that could pretty easily be sorted with a database tweak.
Thanks again, though, for your responses. Makes me feel a bit better.
