I have been unable to withdraw bitcoins for the past 36 hrs.
Another member received an email that there are issues with BTC deposits and they will be issuing new deposit addresses.
https://bitcointalk.org/index.php?topic=914565.0Go to Bitstamp and check your Deposit page, see if there's this large red warning that says
"DO NOT DEPOSIT TO PREVIOUSLY PROVIDED BITCOIN DEPOSIT ADDRESSES. Deposits sent to previous address will not be honored. New deposit addresses are forthcoming.".
. It was more or less off-topic here anyway.
