just folow these steps ...
1) Close all DigiCube wallets that are running
2) Backup wallet.dat in as many places as you feel comfortable with
3) Delete all files in this data directory, but leave wallet.dat and DigiCube.conf here
4) Download the Bootstrap for block 500k here:
http://freestaking.com/downloads/wallet/DigiCube16-Bootstrap.zip5) Extract these two files to the same folder as in Step 3
6) REMOVE ALL NODES. Use these two, and only these two, nodes in DigiCube.conf, until more people have had time to update:
addnode=46.105.158.205
addnode=98.144.161.18
7) Ensure the only files in this folder are the two blk files from the bootstrap, DigiCube.conf, and wallet.dat

Open DigiCube v1.6 and enjoy the new experience
do we need to do any of these steps, or is just a straight download/installer?
