EPMA Web tier service crashes automatically

Question

Hi,
The EPMA web tier service in our application starts and crashes automatically. I have checked the log files and it is showing me following error :
<Jan 25, 2014 1:48:56 PM IST> <Critical> <Security> <BEA-090402> <Authentication denied: Boot identity not valid; The user name and/or password from the boot identity file (boot.properties) is not valid. The boot identity may have been changed since the boot identity file was created. Please edit and update the boot identity file with the proper values of username and password. The first time the updated boot identity file is used to start the server, these new values are encrypted.>

I tried updating the file boot.properties by entering the user name & password in plain text. Still the error persists. Also the file is nor more stored in encrypted format but is stored in plain text.
Any help is appreciated. Thanks in advance.

Because Weblogic is up and running.
Try to start Weblogic again after changing the boot.properties(Username and password).
It will ask for username and password at the time starting weblogic, give correct username and password.
It will come up(max) then try to access.
I did once the same thing as shown below link,
