New wallet not work for me, but I must say that you guys did a good work, Thimo, new Flappycoin dev and others... you pick this coin from dust and give a new life to our little bird. Cheers

Don't worry, wallets safe and will work with the new wallet posted in the future.
Complete rewrite, stable as a mountain. No more horrible coding to deal with or clean up.
In the mean time we'll need known people who we're having issues with wallet to let us know. You'll be the first ones getting new wallet.(During the launch)
For anyone reading this is not happening till after block 110,000 for the new wallet, it will be compatible with previous versions, and updating won't be a hassle any more.
Thank you for your patience in the mean time for anyone suffering incompatibility issues. The only positive to that situation is it is a small number of individuals it seems but we are fixing it.
Sorry for asking this, but I don't get it. When will we lose our coins if not updated?
I can probably explain it like this. You never lose* your coins. The issue of being on multiple wallets or forks is you can not ensure where your coins are going, so you may send/receive and the user you sent would never receive them, or likewise you'd never get coins due to incombatibilities due to wallet software.
That said; as long as you wait for the new wallet it will import your wallet.dat. Losing coins is half the fault of the user in a lot of ways.
Also since wallets are using same protocol version they will be compatible to transfer your coins. It just is a little bit of a wait for people with incompatibility issues.
We would push out new wallet sooner, but it is confusing to do so to everyone that has already waited. So we chose the best case scenario is to ensure quality of new software/wallets and release shortly after block 110,000 to avoid confusion for people who have updated, and to not be continually pushing a wallet out.
* To be fair, it is possible for wallets to not be compatible, but that would only happen after months/years of letting a wallet sit while updates happen and you never update to them. Such as what happened to a lot of bitcoiners who tried to restore wallets that were years old and those coins are forever lost. This is not our situation however, because like explained this is a small time frame and protocol versions will be the same initially and for awhile.
