To install this mod correctly do the following:
Navigate to where you unzipped the mod to and open it up. Select the 'MODS' folder and right click on it. Select copy. Navigate to your 'UbisoftSilent Hunter 5' folder and open it up. Right click in an empty area and select paste. Enable 'NewUIs_TDC_6_6_0_ByTheDarkWraith' via JSGME FIRST then enable any additional add-on mods you want (this assumes you setup JSGME to use the 'MODS' folder as default)

NOTE: is this mod perfect? NO WAY. It will continue to evolve as I learn more about the files and the game itself. Does the mod contain any bugs or errors? I hope not but to say it doesn't would be foolish. I will address errors/bugs as users find them and post them in my UIs thread. If the automatic mast height function isn't working correctly please start the game with Admin rights (right click the SH5 icon and select RunAs-->Administrator)
