How to restore a ripple wallet, having the security key? If I try to login to ripple.com I get this message

Fetching wallet...
Payward  Wallet not found (Username / Password is wrong)
Local browser  Wallet not found (Username / Password is wrong)


It might be a bug, but let's assume I actually somehow corrupted my password.

Luckily I still have my security key, but I've no idea on how should I use it to restore my wallet.
Following these instructions, after clicking on Create a new wallet, you will have the option of using a custom secret key.
