Hi AJ, best bet may be to click the "Need Assistance?" link next to username on a PC Browser or try the "Forgot Password?" link in the BB Browser next to the Password box.
the URL for your Service provider should be:
For 3
https://bis.ap.blackberry.com/html?brand=three
otherwise replace "three" with the name of your service provider in Indonesia (ie indosat) and that should bet you there.
