BD-Live login password

[weehaggis]

Is there anyway of retrieving a forgotten BD-Live account password. I created an account when using the BD-Live features of Transformers but unfortunately forgot the password I used. I can still use the live features on this disc as login info was saved.

Now trying to login with Iron Man disc using the same user-id. I assume it is the same as for the other disc (otherwise having the create a seperate account for every DB-live disc you have would be REALLY STUPID!!!), but having forgotten the password have not been unable to do so.
Point 1 - there appears to be no way to retrieve passwords, or is there??
Point 2 - if a login can be remembered for one disc, why would this not work across other discs?
Point 3 - why doesn't the text entry interface not work with keyboard ?

Thanks for any help.
