okay this is frustrating....

I did everything and cracked the application.....

and I'm looking at "Well done, you did it!" message...

but I don't see any password in that message box or any other place I can imagine to help me claim points in hbh web.....

Am I missing something?

I don't think I am...

There are two ways to crack the app:

1. The harder way: Trace through all the code until you've found the part, which creates the key. Read it completely until you've understood it and create then a keygen or create a program which bruteforces all possible passwords with this algorithm.

2. The easier way: Put a single breakpoint and look what the application is doing with the key you've entered. Look at the stack or the CPU and enter the string the program expects.

Just patching the app like you did doesn't work here, because the app constructs the final key with an algorithm instead of reading it from some strings in the file.
