Hi
Ok we've all had to start again ;-)
step one is to start up your own msql admin tool ie phpmyadmin, I use navicat.
Step 2 log into your database and select all the tables.
Step three using the menu select sql
at this point you should see an sql file created and be asked where to save it. REmember where you do!!!
Step 4 highlight all the tables and delete them.
step 5 start up you new fresh copy of PS3 and let it create the database.
Step six go back into your mysql admin tool and find the option to run your sql file ( see you need to know where it's saved ;-)
that will replace all the created tables with the old ones.
That should solve your problem.
Note that is your existing problem is being caused by your basic settings which are stored in the table wa_settings then by running the sql you will just re create your problem.
If thats the case then when you do your initial SQL dump highlight all the tables except wa_settings. when you restore your new settings table will not be over written.
