Thank you for your response Mr. Gamble. I am greatly heartened to learn that this is some kind of glitch and hope to see it solved. The EA tech representative I chatted with insisted that to use the DLC I had to be online and there was nothing I could do about it if I can't be on all the time. This is the reason I got so upset, as I believed what he told me during our session.
As suggested, I turned off both the auto login feature and the upload gameplay info feature in the online section of options. I connected to Cerberus, loaded a game with all DLC, saved and exited the game. I then disconnected from the internet, as soon as I went to the main menu I got the error message for authentication of all DLC listed and again I can't load my save because it says it is missing Zaeed and Normandy Crash Site.
I am in Win XP desktop using the Collector's Edition with all currently released DLC installed and the 1.01 patch. I can provide my comp stats if necessary, however I am not using a Mac nor multiple addresses as you noted in your post Mr. Gamble.
Unless I am literally not doing something that has to be done to authenticate the files after logging into cerberus network and starting the game with the DLC., I'm going to guess is some sort of bug as mentioned with my platform.
Hope it can be fixed, thank you all who responded and tried to help.
UPDATE: For Mr. Gamble or any devs, I hope this helps to find the problem. I got it to work offline with the DLCs, but I had to do something strange to do it. While connected to Cerberus, in the main menu I hit the download content tab which brought me down to desktop but keeps the game running. Here I disconnected and when I returned to the game's main menu I got an error message that there was an interruption in the cerberus network and connection failed. However I loaded the save without problems. I then exited the game twice and started from scratch twice and it continues to load the saved game with the DLCs, I tested it directly on the planet with the Normandy's crash site.
If I turned off the game disconnected and turned it back on, it always gave me an error before. But after I disconnected while the game was still turned on, it seems to finally have made that authentication file I hear so much about. Obviously I assume it's not meant to function this way (By having to disconnect with the game still on) but at least it works the times I tested it.
So maybe there is a problem with that file that supposedly is made when logging into Cerberus to authenticate the DLCs and you turn off the game completely (It erases it for some reason?) so it always asks me for the authentication again? Hope this helps you guys piece this together.
Thanks and I'm keeping my eyes out for a resolution for this.
