That is a known thing.
Check if you have all Tinytip directories inside your Addonsfolder:
TinyTip
TinyTipOptions
TinyTipExtras
TinyTipModules
You probably have only one inside your AddOns Filder called TinyTip.
As far as i know Docevl fixed that in one of the latest packs. I presume things go wrong when you use WAU without Externals, but i'm not sure about that.
Anyway, geht the missing things here:
http://files.wowace.com/TinyTipOptio...TipOptions.zip
http://files.wowace.com/TinyTipExtras/TinyTipExtras.zip
http://files.wowace.com/TinyTipModul...TipModules.zip
Install, login and you should be able to access tinytip config by typing /ttip or /tinytip ingame.
Hope that helps you
