Despite our best efforts, YoBit has thus far not responded to us regarding the coin swap. We will continue to reach out to them, but for the time being the only advice we can offer is to withdraw your BITS from YoBit to your own local BitStar Wallet before the swap, so that you won't lose your BitStar coins. For Windows you can download the current version of the wallet here: https://mega.co.nz/#!lMU3WQ6C!CUq9wM-9jUq0aYMjwRd1QPI-H5U0xO-ElebNXa1jEck

And then you can use the new FastStart pack to get synchronized quickly: http://www.mediafire.com/file/8oyb03xsvbktx7a/Bitstar_v1_windows_faststart_25-01-2018.zip
