Can't connect after changing BI Publisher Administrator password

Question

I have a single machine instance of OBIEE 10.1.3 on Windows. All elements have been working fine and I have been able to successfully sign on to:
1) BI Publisher
2) Dashboards/Answers
3) BI Administrator
However, today I decided to change my 'Administrator' password in BI Publisher for good order's sake. And now after making that change I get an error reading:
{color:#0000ff}*'The server can not be used due to a configuration error, please contact the administrator. If you are the administrator, please consult BI Publisher user guide for proper configuration'*{color}
With 'error detail' reading: oracle.apps.xdo.security.ValidateException
Using the old BI Publisher password also returns an error (invalid user/password). I also stopped and started OC4J service all Oracle BI products. My BI Administrator signon still works fine.
I've read several posts about failed connections like this and ran across one that implied that characters in the new password such as *, #, $ will create problems. Unfortunately my new password does contain some of these characters {:>0 and I suspect this may be the issue My question: What is the least complicated way to back out of this situation and simply restore my sign on? I'm totally focused on data architecture and reports on this single user system right now.

Madan,
Thanks for your help.
The password in xmlp-server-config.xml is encrypted. It looks (similar) to this:
<property name="BI_SERVER_SECURITY_ADMIN_PASSWORD_ENC" value="C14CD2495C033BB8E816E10BCDC25372" />
<property name="BI_SERVER_SECURITY_ADMIN_USERNAME" value="Administrator" />
I tried changing the encrypted password to my password but got a java sign on error.
I then modified the last block in CredentialStore.xml and restarted the BI Server and OC4J but I still get the 'oracle.apps.xdo.Security.ValidateException' error when signing on to BI Publisher. Here's the entry with the (dummy) password which
I tried with the first change above and without the first change above.
<!-- This credential is used for storing the username/password that is required
for SSO impersonation in BI Publisher. In this example, the passphrase is shown inline. -->
