Hi,
Sorry to ask, perhaps it has already been discussed a few pages ago, but don't seem to find any relevant information search - any hint how to make the old key (wallet.dat) work? The new client has been completely upgraded, so not really sure how to make it work.
Thanks in advance for an advise.
Wallet.dat is not the same in Qt wallet and client. In Qt that file is your key, and if your wallet.dat comes from Qt you need to use Qt in order to access your account. You can then transfer your coins from there to an address created in client.
In client the key files are named key1 and key 2 by default.
