Error during migrations using Community Engine

Hello all,

I use community engine in my web application.
when I create a new application and integrate CE it works perfect.
But when i integrate CE in my application it is not working.

please give suggestions.

My problem is that --------

my application has database “aflatune_development” . I setup CE in my
application as per instruction given at “http://communityengine.org/
documentation.html”.
It create migration file in my “db/migrate/
20090408130952_community_engine_to_version_61.rb”

Before this my database contains two tables “roles” and “users” which
are also present in CE
so i renamed my these two tables first and then tried.

when I execute migration using rake db:migrate,
It executes some migration and then throws error that

rake aborted!
An error has occurred, all later migrations canceled:

following is some executed migration and error
