NASLite Network Attached Storage

I purchased a new copy of NL2 x64, setup went fine.

I configured network, entered licence ID etc, and then changed the password as per the manual.

The password was accepted once I typed it in the 2nd time, so there is no typo with the password.

Saved settings and rebooted.

NL2 now refuses me access - keeps saying Login incorrect.

I have triple checked that I am typing the password correctly.

Any hints as to why this should be?

EDIT: was able to login using lower case, not upper case as was used in the password setting option, which is odd.

Example: Set password to ABCDEF and have that confirmed by entering it in twice. Save and reboot. ABCDEF rejected, but abcdef accepted and I'm in.

Any reason for this?

ANOTHER EDIT: Reset password again. Working the way it should now. I have a feeling I had the CAPS LOCK button on, following the entering of the licence ID, so then holding SHIFT to set the password to upper case, would have in fact set lower-case.
