Thanks for coming back so quick. Yes I created a database (via importing store.sql) and created a user for the database in WebAdmin. I changed the name to ensure that I had the right detail in the right spot - hence the naming convention so you could see what I was entering and where.
Looks like l may be entering the correct detail without having any luck. Are there any different syntax changes between MySQL v4.x, 5.x and MSSQL? This is really bogging me down - is there an alternative way around this?
