is anyone aware of issues with domain mapping and the wp

Hi is anyone aware of issues with domain mapping and the wp Multi Network (3rd party) plugin?

Mapping isn't working and some multi-site registrations are going to "Error establishing a database connection".

See http://countrie.wpgoodtogo.com/ - this is a standard multi-site account (not working)

While http://studioleeds.wpgoodtogo.com/ - this is working but it is set up as a network site (working as a subdomain)

Neither will map to a top level domain - see http://www.studioleeds.co.uk
