Version 2.07 = 2.08 and Version 2.09 = 2.11.

The numbers are slightly off because the numbers were set in development Versions that were too buggy to be released. So if Dominions says you are using Version 2.07 you are using an older Version or at least you have played your turn with an older Version. Try to play your turn again before connecting to the server and see if it works.
