I use WAMP and the text file seems to be created when the install has done.
Ok re the database as far as I am aware a mysql database contains two parts information scheme and the database you named before running the install.
If you are working on a localhost I'd create a brand new database and start from scratch.
Finally No I'm not on the payroll my experience is limited to a few months re mysql but I have been writing websites for several years,
So I'm on a learning curve as well. In fact I've still not got a working PS3 shop but I'm working on it.
