Warlords Battlecry II v1.03 new protection?

[GCS]

I think that the new 1.03 patch changed the protection used to a newer version (maybe like Stronghold 1.2 patch did).

A copy from my original Warlords Battlecry II used to work with the official patch version 1.02 without the need of any no-cd/fixed exe but doesn't work anymore with patch 1.03...
