Many custom UIs that people use aren't updated these days, in my case Corruption, so here's a list of stuff you have to do to self-maintain them that should work for the majority (if I missed stuff which is possible, post what I missed and how to fix, or if you have better solutions, share.).

All the things you have to change are in the "Customized" file directory in the GUI folder.
- If your damage numbers are coming up black delete "TextColors" to get the default colours.

- If your mail GUI is not lined up and you can't send/get mail, delete “mailview” in tradepost GUI

- Feat planner not working?
in "mainsplitview"
Code:
hotkey      = "Toggle_SP_Feats"
left_module  = "SPFeatsLeft"
right_module = "SPFeatsRight"
change those lines to these;
Code:
hotkey      = "featplanner_window"
left_module = "FeatPlanner"
right_module = "FeatPlanner"
