You've got problems with addy generation:
3EQq6CXbtcd3SPmQ1PWPzBWrD4XaXHChKF is not a valid address, such as all that your system generates. I sent $80 to this address, please do somehow and give me my money back.
I just tried to generate a few addresses using E-coin and all of them works fine when I check them on the blockchain.info , my guess is that you added something to that address .
Either way , while you are sending using a wallet (most of the known ones anyway) , they should check the address (If it's valid or not) , If it's not then you won't be able to send.
Please post your Bitcoin address you sent from so we could check the transaction and see what really happened.
