Thought I'd make a separate thread on this so people will notice it.
1.0.2 apparently broke loading the add-ons properly when placed in the \Data\Gui\Customized\Flash\ directory.
When doing these changes you might have to restart your client.
What you need to do is to copy the .swf files from \Data\Gui\Customized\Flash\ to \Data\Gui\Default\Flash\, but before doing so make sure to rename any of the original files in \Data\Gui\Default\Flash\ that might get overwritten (like MainMenuWindow.swf, FullscreenVideoPlayer.swf etc.).
This is so you can restore them once it's fixed (likely with the 1.1 patch).
When it's fixed you should also remove files that were copied over, which means all custom files that didn't already exist in \Data\Gui\Default\Flash\ previously.
You do not need to change/move/copy any XML files.
Some have said the above doesn't work for them, in that case add the following line to MainPrefs.xml, LoginPrefs.xml, CharPrefs.xml and Modules.xml located in \Data\Gui\Customized\
<!-- $Change: 310823 $ (must be within the first 200 characters of the file) -->
For TextColors.xml add the following line to the file in \Data\Gui\Customized\ - overwrite any similar line if it already exists.
<!-- $Change: 310823 $ (must be within the first 200 characters of the file) -->
Right now the patcher doesn't seem to overwrite the changed files, which is good (but possibly an oversight as well) in the current situation.
Enjoy your add-ons once again.
