I can't find your username in my copy of the dump of the old database. If you send something to me in an IM (NOT a profile post!) containing the email address you registered with on FCN (if you ever provided one) and all forms of the username/usernames you used, I'll see if I can find anything that way.
I think you, like pretty much everyone, misunderstand what happened, though. When the forum was created, everyone needed to register to preserve their username, and *if* the username was invalid (contained spaces, started with a number, contained non-alphanumeric characters, etc -- we didn't leave this for the users to figure out, we let the forum tell them whether the username was invalid or not when they tried to register), it had to be changed. Many were able to create the exact same username as they had been using before, which left their credits in-place and accessible to them with no trouble whatsoever. Many registered a new username, requested a credits transfer in this thread, and got their credits. Many registered a new username even though their old one was perfectly valid, which just created more work for us. Many never even noticed the forums, even though we posted links in the chat and encouraged people to spread the news, so they had no idea what was going on.
There were some problems tracking credits because of 123FlashChat itself, which is just one of the many reasons we stopped using it (foremost, it was no longer supported and updated to resist tampering by hacker wannabes). People would register a username, log in, and then immediately change their name to something else. For instance, you're "Ellie." You might have logged in and changed your name to "Bellie" every day, which would prevent any credits accrued as "Bellie" from transferring to the "Ellie" account. This was a known issue and limitation of 123FlashChat that users were informed about any time they complained about it happening. Moderators and admins were informed, the information was repeated, but FCN has thousands of users so everyone forgot, and kept arbitrarily changing their usernames all the time. We disabled the ability to change usernames on-the-fly in order to prevent this, but the software reset itself eventually every time, and people started "mysteriously" losing their credits. Yet another reason we ditched 123FlashChat and have no support for arbitrary username changes whatsoever. Anyway, because of this particular issue, in some cases, credits just weren't anywhere to be found in the 123FlashChat database. And because 123FlashChat didn't keep a record of all the arbitrary username changes, there's no way for us to tell a) if this is what has caused the problem for people who are now complaining that they didn't get their credits (many users I had *personally seen* changing their username at random swore they never did, so I'm not taking anyone's word for it) , or b) how many credits such a person might have had.
In any case, we're free of 123FlashChat now, and there is no reason I can think of that this should happen again. We have control of all software we're using now, and the chat is developed in-house. There might be people who must have their credits left in the old chat because of problems with 123FlashChat we had no control over, but going forward, those people can still accrue credits through chatting in rooms and doing things on the forums. It's a small setback, since there isn't anything to spend credits on yet anyway. Gift systems are still in development.
