Redeeming commendation packs is is causing troubles with DLC / online pass

I had troubles with the authorization of DLCs / online pass three weeks in a row now. Whenever i redeem a commendation pack, one of my DLC cannot be authorized any longer.

First time the game was asking for a online pass, which is not existing since i´m playing on PC (collectors edition, Win7Professional64Bit).

Second week it was kicking out the main game (collectors edition and Through the ashes-DLC).

Third week it was the firefight  DLC which was kicked out.

In all three cases the EA technical support (starting with chat and ending in a everlasting telephone call) was able to help somehow.

But the last time it was already quite a workaround by the technical support to make it work again.

Is there anyone else having these kind of problems, or is there a hint whats causing this.

It would be really annoying if i would have to call the hotline on a weekly basis to get the game working again.
