Still ok with the original wallet, don't need to upgrade or anything?
Client YES
Wallet nope, if your wallet needs updating with a newer client , the client will auto update it.
If you have transactions on a forked chain, it gets a bit trickier, but it is much easier if one keeps backups of their wallet like everybody does....RIGHT???...
lol, well never actually used it so no issue in getting a new one. it's stuck it seems updating blocks.
