I have sent multiple emails on my ICO claim and no answer yet i need help i used my mycelium wallet sent screenshots of all info where it was sent from and got the money they sent to addy but it will send from another addy if i send that acct changes addy everytime i send one
IMHO you have created a HD wallet in mycelium and that's why you can't control your sender address. Try sending your complete balance to the address with which you participated in the ICO and then try again. If you have all bitcoins in one address the wallet is forced to take this address as input.
Good idea CryptKeeper, please try this bigs21024, this should work. Send your balance to the address that you sent using ICO, so it will send inside your wallet to that address, and then make the ICO verification payment, and it will come out of that address.
