I have not used this host before but try this connection string and see what it gives you.
It clears the name first then I have removed some space you had in and told it to use a
sql provider.
<connectionStrings><clear/><remove name="StarterSite"/><add name="StarterSite" connectionString="Data Source=saffron.arvixe.com;Initial Catalog=StarterSite;User Id=root;Password=****" providerName="System.Data.SqlClient"/></connectionStrings>
Also if that does not work try adding Integrated Security=false"; into the connection string.
