What is being described here shouldn't be possible. The same script does the logging in from where ever you try to log in at.
Make sure the password is exactly what has been sent to you in the email. The passwords are case sensitive. If you can get into the bank, then you should be able to change your password to whatever you want.
Let me know if this problem persists and I'll take a look at the account.
