I just completed the last level of the original kingdom rush vengeance and learned about the dlc. I bought and installed it but no new content has shown up and the version number on the launcher as still the same as before installing the dlc. What can I do to fix this?

Edit: Yes I realized it's called Hammerhold instead of Hammerhead after I created the thread.

I fixed it! Turns out I had to manually install each update first before installing the dlc.
