I added Arien's GUI to my install some time ago and also ran into some /showfile issues.
It took a little while scratching through all the files. As all the paths changed it is a matter of fixing the relative paths that have changed. In all the .htm files.
There were a couple.
Basically this is what it should like for all the showfile things....
This is from C:\Users\PROFILENAME\AppData\Local\Funcom\Anarchy Online\RANDOMHASH\Anarchy Online\scripts\AOU_mod\AriensGUI\WhoBuffsWhat.htm
Code:
Abilities
<font color=CCInfoHeader>
<a href='file://../AOU_mod/AriensGUI/BuffPanels\Skills\StrengthBuffs.htm'>Strength</a>(<font color=CCInfoText>Str</font>) - <a href='file://../AOU_mod/AriensGUI/BuffPanels/DocBuffs.htm'>Doc</a>, <a href='file://../AOU_mod/AriensGUI/BuffPanels/EnfBuffs.htm'>Enf</a>, <a href='file://../AOU_mod/AriensGUI/BuffPanels/MarBuffs.htm'>MA</a>
As far as I remember, it's the "file://../AOU_mod/......" that had to change. I don't have time to check the virgin files I have lying around right now.
And as B pointed out. All of this goes into the hashed folder in my case:
Modify to fit your own folder structure...
C:\Users\PROFILENAME\AppData\Local\Funcom\Anarchy Online\RANDOMHASH\Anarchy Online\scripts\AOU_mod\AriensGUI
EDIT:
Forgot to dump this in here. This is the apanel file in \scripts (From the above location):
/showfile ../AOU_mod/AriensGUI/ArienskyPanel.htm
