Router Help?

Ok, stay with me here, cause I feel pretty stupid.  Months and months ago, I set up a D-Link wireless router at my parent's place.  I lived at a friend's for a while after that, so it didn't concern me, but now I'm back and need to use it again.

The problem is, I can't login.  I go to my router's IP in IE, and it gives me a password prompt.  I put in admin and leave pass blank as per the manual (I'm real lazy, and didn't think I even changed this when I set it up) but it didn't work.  Now, stupid as it may be, I only use two passwords for everything--no matter what.  It keeps things simple; I can change if I need to, but it's easy to deduce which it is if I forget.  Unfortunately, it's neither of these.  I tried all combos of capitalizations, etc.  And I CAN log in as a user, but that's useless as I can't change settings.

So, anything I can do as far as resetting the pass or getting in?  Once again, I know I'm retarded for not writing this shit down or something, but I really need to know what my options are.

No, they're not long at all, around 9 characters...and oddly, when I log in as user it shows the admin and user passes to be very long, around 14-17 characters.

There's a reset button on mine as well.  I pushed it and all the lights flashed green, then went back to normal.  Then I tried logging in again, and no dice.  Hmmm...
