verification of the date of release has error there during the validity date

Can you try checking the game for any updates. Right-click the game panel and you should see the option to do this.

Thanks. 

I tried EA_David's suggestion above, and it worked. However, could you make the information a 'sticky' and post it more prominently. I downloaded and installed the Patch (1.04), and validation was very easy. I would point out though that I did have to make numerous attempts as I kept getting 'Error: ty again later' messages. I persevered, and now appear to have a working game.

Re-installed Dragon Age 2 on my computer (the one it was originally installed on). Cannot get it to date verify and SecuROM is no help. I have an authentication code if necessary.

@Chillearth Hey, are you trying to play an digital or disc version of the game? If you're using a disc version can you ensure the game is added to your Origin and try updating the game there?
