Sorry - sussed out why it wasn't working correctly; I dumped the data into the DB first then installed the product - which wipes the table first, so removed everything I just uploaded!!
For anyone having problems getting the Dictionary into the database, try this:

It can dump very large sql files into the database in small chunks, very simple and works extremely well, and doesn't crash out your database!!
Cheers
