DataTables 1.9.4 CSS Not Being Applied ?

Hi,

Firstly as this is my first ever post here I would like to say what an absolutely outstanding piece of work DataTables is.

My problem is that I have a DataTable that works perfectly using DataTables 1.9.1 however when I upgrade it to using DataTable 1.9.4 some of the CSS is not being applied, i.e. specifically...

table.dataTable thead th
table.dataTable tfoot th

table.dataTable tr.odd
table.dataTable tr.even
table.dataTable tr.odd td.sorting_1
table.dataTable tr.odd td.sorting_2
table.dataTable tr.odd td.sorting_3
table.dataTable tr.even td.sorting_1
table.dataTable tr.even td.sorting_2
table.dataTable tr.even td.sorting_3

I am using exactly the same CSS file I created for the working DataTable using 1.9.1 and don't understand why this is not being applied ? Maybe something has changed between DataTables 1.9.1 and 1.9.4 in the way CSS is applied that I am unaware of, and I need to change my CSS or HTML Table classes ?

Any help would be very much appreciated unfortunately I can't post a link to the page as it is residing on my companies intranet :o(
