Can't Install any of the Themeco Headers or assets

I just installed a new WordPress site and didn’t add any plugins or change any settings. The only thing I did was install Themeco Pro and then in Cornerstone selected any of the Themeco Headers (1,2,3,4 + 5) and none of them were able to install.

Uh oh!
Failed to create Header, unknown compression type 33990

I’m trying to install the Starter Site and nothing is happening.

Try again now. We had to update something on our end.
