Go to WTF folder,replace few things inside with YOURS(check all folders inside).Log ingame change your UI scale to 1(far right). Type /reflux switch keepo ,close the game and enter again.
EDIT: Most of the UI(around 90%) was made by KRIPPARRIAN(all credits to him).The UI is for 1680x1050 resolution,so if u have different resolution,u will have to move the addons ingame manually(or play with the UI scale).I also recommend to delete your CACHE and LOGS before using the UI.
