Changing password gives me leaf network adapter error

I've had a similar problem with changing passwords.I don't know my old password, but upon changing passwords, the new password continually gives me the Leaf Network Adapter error.

Strange, because I've been able to login with other people's accounts with no problem at all on multiple occasions both before and after the password change - and I've tried this on 3 different PCs, 2 running Windows 8, and 1 running Windows 7.

I don't know what's going on with these password changes, nor do I know how to fix it unfortunately. Just seems like something is broken with the ReadyNAS Remote password changing that invalidates the new passwords, and causes the client software to throw up this erroneous error.

Hope you find a solution soon!

Edit: I even tried deleting my account in the hope that'd fix it, however upon creating an account with the same username, it produces the same error! Very strange!
