OK, I got this issue resolved.  It is a bter bug and not something that had to do with having oversold the balance.  I knew that there was no way that I oversold my balance.  

What you should do to resolve this is to install the imqq (do it on a computer that you don't use to trade your coins if you don't trust the QQ program to not steal your info).

add all those bter support QQ IDs to your contact and wait for the China working hours to IM them, IM the QQ IDs that show that they are online (green dot status).  Some of the support people understand English OK, but most don't understand English at all and rely on the translator to understand the message.  So, keep your IM messages short and simple, tell them that you have a coin withdraw problem. Tell them your account ID and tell them your error message (don't worry about hiding the error code, I think they are just your transaction balances).  

If you are lucky, a competent person will take your account ID and your error code and tell you that you have an account imbalance of a coin type and that you need to "top up" with a certain amount of that coin.  If you are not lucky, you will exchange several messages before you get passed to a competent person.

You can use your current BTC balance to buy that amount of coins or you can transfer in the required amount (buy/transfer in a little more just to be sure).  

If you are brave and have a large reserve of fund, you can just buy/transfer in the coin that is giving you the error message to increase your balance until the error is resolved.  This way, you don't have to wait for support.

After that, the error/bug will be fixed and you will be able to transfer out your coins.  They make it sounds like you have a negative balance, but you don't, it is just some bug that they have.  You don't actually lose any coin after you "top up", you can just transfer out the balance after the bug is fixed.
