And what is the amount in question? The last numbers in the error code? I have: FTC-1304--23--0.8996 so do I have to buy 0.8996 FTC to solve the problem?
EDIT: That didn't work. I buy 3 FTC but the error remains.
You may wish to try 30 FTC, then sign out of your account and sign back in and try the withdrawal again.
If that doesn't work, maybe try sending 30 FTC from your wallet to your Bter.com account, then try the withdrawal again.
You may end up with "Too many tries, please try again later."
