Never heard/seen this behaviour before, and I've installed from disc and Origin onto both Win7 and Win8 (multiple times. Long story...)
What mods?
What mods? What do you mean? I haven't installed any mods up to now, if that was your question. I only have the clean versions of the game & DLC. I find it strange that all DLC are missing text, why would that be? I haven't found any solution no matter how long I looked. I think I'll start Legacy without subtitles nor dialogue options, and hope that there isn't much dialogue cutscenes in it... =/
EDIT: also, noticed that in the Achievement panel through the main menu, none of the DLC-related achievements have a description. They're just blank, with the normal shield picture.
I have the exact same issue. I play on Win8 (I HATE win8) and I bought a physical copy of DA2, but I bought Legacy on Origins. I do not know what to do about this bug ☹️
Ok, I download Legacy from Bioware social site and now it works. Guess I shouldn't have bought legacy on Origin...
