I've just received the mail about the Official MUSE Launch
According to the mail I'm in the B Section : "For those that never claimed their Notes and decided to wait until the real blockchain came out"

All I have to do is : "to import your Bitcoin Private Keys (the wallet file) into the MUSE wallet"

My stupid question is : Where can I download the "MUSE wallet" ?

No link where provided in the mail, it should be obvious...
