I also had a humble bundle key for Burnout Paradise The ultimate box
I also encountered problems -
While launching it an error popped up saying that license limit has been reached for this product
I went on to the game folder and found a configuration file from Sims 3, I downloaded the right configuration file, replaced it and it worked!
That could problem for you too. Check the folder thoroughly.
What do you mean? I activated the product but like when I try to launch bf3 it ask for a product key and when I use the product key I was given it says it is not acceptable.
