Re: [EA app] Dragon Age 2 DLC Cannot Authorize Error
@Aria1 I kind of expected it to happen. Go into the documents folder or wherever you have the DLC installed and delete all of it. Then repair the game and redownload it.
With mergers since it's all technically now on a different account, it needs to authorize the right download. The PC could be seeing the license and servers trying to activate something you don't own.
This is was a big thing years back. Way before the EA app. What I do is I use a registry cleaner. You don't have to but if there is one you use, delete everything and clean the registry before you reinstall it over.
Your PC, unless cleaned out, will try to use the registry to validate those files and if you don't own them or the account doesn't any longer, you will get an error.
