stop your current mist wallet.
current mist version is 8.1 (i believe). update, when you fire it up it askes which chain.. new forked or old one. pick one.
then let it update the blockchain and see if it shows.
I just noticed that my wallet is version 0.7.2. Do I first need to do the update to 8.0 before I do the update to 8.1?
Thanks so much! Im not a techie
