Vista/W7: If your boot disk is not C: and you (re)install LotRO, it seems to put things to "C:\Users\%USERNAME%\AppData\Local\Turbine\The Lord of the Rings Online" instead of what I would personally use: "%LOCALAPPDATA%\Turbine\The Lord of the Rings Online". I know this because my %LOCALAPPDATA% is "F:\Users\gary\AppData\Local" but the custom files I was intending to use (and assumed would not be touched) after the reinstall were in "C:\Users\gary\AppData\...". These are now gone. Why does the client install even remove these files? Who knows, but just be aware.
Why am I homeless? Why do all you motherfuckers need homes is the real question. They called it The Prayer, its answer was law Mommy come back 'cause the water's all gone
