Downloaded new wallet (v0.15.1.0-gba8ed3a93be 32-bit) and creted new address with it.
Tried to copy it to suprnova but it says "Failed to update your account: Invalid coin address".
Doing something wrong?
Did you try to send using the conversion tool between new and old addresses? (pools and exchanges still have the old addresses):
