Just experienced a delay myself. Had the usual pop-up claiming the unlocked achievement, however it didn't show up in the list.
However, after a couple of hours, they magically appeared. Confusing to say the least. Also using retail, without any trainers.

I would be happy with a delay. I've just got a big nothing under my achievements. It's hard NOT to get a few of these, so I do know it's not my playing.
I even tried it without the trainer and still the same. Didn't really think that was the problem anyways. But since the Steam people can't be bothered responding, I thought I would come here. You lot are nicer anyways.
Someone said something about Steam-overlay? I don't know what it is, but I haven't changed anything that I haven't already mentioned. All other games are working and unlocking fine.
