<MaNGOS> mangos vs mangos

I have recently upgraded my server to the new MaNGOS V2.0.10 BC.
I dumped my old DB's (mangos and realmd)
and created the new DB's mangos_bc & realm_bc every time I tried to run them under the new name I would get an error ONLY when starting the mangos_bc saying:

2007-04-10 22:00:12 World Database: 127.0.0.1;3306;root;mypassword;mangos_bc
2007-04-10 22:00:12 ERROR:Could not connect to MySQL database at 127.0.0.1: Access denied for user 'root'@'localhost' (using password: YES)

2007-04-10 22:00:12 ERROR:Cannot connect to world database 127.0.0.1;3306;root;mypassword;mangos_bc

I had tried everything with help from various people on this forum to no prevail

so last night I created a new folder Named MaNGOS on my C drive and named the old folder Mangos_bak

I dumped MaNGOS V2.0.10 BC into the new folder
and then proceeded to Create 2 new databases on my SQL server...
mangos and realmd... (Without the _bc attached)
I then Import the 2 SQL files from the SQL folder into the appropriate databases...

started both services AND IT WORKED WITH NO ERRORS......

My Question is WHY will it work without the DB having _bc attached to them but will work fine without them????
Is it something im my Original settings?
please help!
