I am running the english patch and forgot to replace the original lang packs,well it patched with the one error message on the launcer but i am playing the game fine and I was able to do UD7 just fine but I had 6 wagu coins left over and i went to use them today and on all 4 wagu machines i get the error message DST_WAGU_ITEM_ASK_EXCUTE_WP, any help would be great thanks

Yep, im having the same problem. I gave my account to a friend, and he wasnt able to play it on his computer too.

That "error" pop-up on the launcher isn't really an error but more of a notice that the launcher has finished patching, now for that weird error message you get in game try running the setup as administrator and clicking the 2nd option which is repair and then try again.

Re-install dbo. Dont install the enlish patch. worked for me

Correct, I re installed its all good now!
