Finaly got my tokens swept from electrum wallet to counterwallet

hello friend! i also invested using electrum, how do i get the coins if you don't mind helping, i only used electrum for this ico so its new to me.
thanks
Create an address on
https://wallet.counterwallet.io/#After you created it, "login" to your address, upper right corner you will se:
- import funds
- from another wallet
- insert private key you of BTC electrum wallet you registred on NVO
this does not work for me. Import (Sweep) Tokens from Another Address just takes for ever and the blockchain explorer tells me:
Unable to decode output address
What does this mean?
EDIT: the NVST has been transfered. although the sweeping thing in counterwallet never finished to "spin".
