I don't mean to sound ungrateful but I know how to setup mysql & how to configure user access I work in an IT department & I'm a SQL database administrator.
I have many databases in my mysql installation, I know the wordpress database is fine as I can import data using the "Import posts from an RSS feed" and that does work but only import the current week’s posts which are no good to me.
I have queried the database and no data gets written to the tables, I'm supprised its not working since in previous versions you have to set the import directory then place the file into that folder and this version gives you the option to browse to the import file so there is no configuring to do.
As a test I exported one entry which was a simply one liner saying "hello" but even that failed to import.
I can provide anyone with a sample of the data I am trying to import if they want to have a go at import it into their own database to see if it works, there might be some issue between MT 3.2 and the wordpress importer. Also if anyone wants to send me a simple entry to import I will try to import that, at present I can not say if its MT's export or if its wordpress that is not functioning correctly.
