So - I am also a bit confused. About 5 months ago, I bought StreamFab lifetime. I now see since then they have released other downloaders, but when I go in to my account, I can either update my license for $129, or buy the DRM MPD for $90. Given the small price difference, I am tempted to just upgrade the license - but I want to make sure that this will add the modules I don't have a license for also as lifetime?

Here's my experience upgrading which might help you.
When I was looking to get the DRM MPD product I was missing a number of other products like Crackle. If I wanted to upgrade Crackle and DRM MPD it would be closer to $200. Or under "Upgrade License" I had an option to purchase an upgrade called "StreamFab All-In-One Lifetime Gift". This is to my knowledge the best option to select when upgrading. For me it was $99 and included any of the products I was missing for $99 ( I think price may vary depending on the number of products you are missing ).
If the $129 cost you are talking about is referring to the above upgrade option called "StreamFab All-In-One Lifetime Gift" under License Upgrade then yes it would add any module you are missing to your account with Lifetine.
