thanks
I have a Coinbase account. I just tried entering that address at Coinbase. It worked fine.
Perhaps you are making a typing error when you enter it? Perhaps there is something wrong with the copy/paste on your computer that is modifying the address when you try to paste it into your Coinbase webpage?
Maybe yes.
Can be identical to my similar problem back to the Bitmixer signature. It has something to do with the browser. OP must tried it first to different browser and check if the same error will happen. Also don't just copy remember to do a backspace if ever the first digit of the address is not exactly beside with the box where address should be posted. Also check if there is a space after the last digit.
OP can also paste it first to Notepad or Ultraedit then do the copying there before pasting to Coinbase.
