You need the new wallet - delete everything in AppData/Fluttercoin EXCEPT (DO NOT DELETE) your wallet.dat and .conf file if you made one. The coins you earned are still possibly good, they'll be verified agains the blockchain in the new wallet and may disappear if they were mined on an incorrect chain.
I however, can't get the new wallet to sync ><
I cant even download it - or google is overwhelmed.
