Time Capsule won't accept my user name and password for access - Help!

Question

Hi all,
My Time Capsule seemed to stop working one day and I had to do a hard reset with the little button at the back. After that it worked and I restored my wireless network settings but now I can't access the Time Capsules hard drive with Time Machine.
When I try to choose it as my Backup Disk in the Time Machine preferences it says "Enter your user name and password so Time Machine can access the file server "Our Time Capsule" (the name of my time capsule). However, every time I try to enter my password I get "Sorry, you entered an invalid username or password".
I've already tried several resets of the Time Capsule and I've also tried logging on my computer as the Root user and changing my administrator account password back and forth but no go.
Help! and Thanks.

Norman & Harry,
Consider the following:
*_Time Capsule Keeps Asking Me For a Password_*
It will be important to know what is going on, or what you are doing when it asks for the password. Is it asking for a password only when Time Machine attempts a backup? Consider this:
It is NOT your username and password it wants when you try accessing the Time Capsule. (I know... it SAYS "username and password") But it means the Time Capsule's Name and Password.
You will find that by launching Airport Utility.
Select the TC on the left.
Click "Manual Setup".
Click the "Time Capsule" Tab.
You will see "Time Capsule Name:" and "Time Capsule Password".
Make sure “Remember password in keychain" is checked.
That is the information you need to enter when it asks for "username & password."
*I Don’t Remember What My Time Capsule Password Is*
You can see what your current TC password is by going into Keychain.
Open your Keychain and select "login" from the Keychains pane in the top left. Highlight "Passwords" in the Category pane from the lower left.
Sort all the items by Kind. Note everything labeled "Airport...". How many do you have listed? There should only be one "Airport base station password" for each base station that you have active. Also, there should only be one "Airport network password" for each network you have created. If there are more than these, then delete all but the ones with the most recent Modification date.
To see what passwords are being stored, double-click your Time Capsules' entry. A new window will appear.
Put a check beside "Show Password". You may be asked for your own Admin password so enter that.
Now the Password field will display the password you entered into Airport Utility for your Time Capsule
*It Still Won’t Accept the TC Name and Password*
Launch Airport Utility --> Manual Setup.
Select "Disks" in the tool bar above.
Click the "File Sharing" tab.
Is "File Sharing" checked? It should be.
What is selected beside "Secure Shared Disks"? If it says "With Accounts" or "With a Disk Password" then the system will ask you for a password every time it mounts the TC hard disk. If you switch it to "With Time Capsule Password" then use the password you designated earlier in the “Time Capsule" tab. It should only ask you once and then never again - because you had checked "Remember password in keychain".
If you have made any changes then click "Update".
Let us know if this resolves your issue.
Cheers!
