none-noun complete in dragon age 2

well, every time I open origin, a box with the download progress of DA 2 appears showing it with 100% and a bloody weird number under it in GB. The funny thing is that I can play the game, but it's impossible to uninstall it, every time I click with the right button in the game icon and click in play, another box appears talking about some update and I ignore it and the game starts normally. This is really annoying, anyone can help?
