Ok, you need to install either the injector or the wrapper, not both. The wrapper puts a d3d9.dll in the Skyrim folder which (I think) automatically overrides the default Windows d3d9.dll and adds all ENB's effects. If I understand right the injector patches Skyrim so that it uses the enbseries.dll.
I've just looked at the batch file I
think you're using, and it would
only. work with ENB wrapper. So uninstall ENB completely, re-install just the wrapper, and try again.
Good luck
