I have a feeling the technical support people are probably more up to date on current games than older ones such as the original Mass Effect, which may explain the 'go-to solve attempt' response you got (and often the 'specialists' aren't very helpful, and take quite a while to get back to you, just a heads up).
Perhaps one of the EA accounts on these forums could be more help (they're all called EA_<name>, so easy to spot, but I don't know which ones are active on this particular board), they're often knowledgeable about such things.
It would be a pity to miss the BDtS on your playthrough if you're doing the entire trilogy, since there are some consequences (depending on your choices) throughout the rest of the trilogy if you do play it.
Well if I could continue my save, then that would be okay, but it seems I would have to start all over again. It just says that my save contains BDtS content and that I cannot go on playing that save whilst BDtS is not installed...🤔
