For just the alien subtitles, it depends which mashup you got, and whether they ported over the subtitles from 1.0 to the 2.0 workprint to replace the missing ones.

No, there were no subtitled Ewok lines. If your mashup includes the lines “I have come for the bounty…” (~14:16), “Bring me Solo and the Wookiee.” (~27:38), and “They will all suffer for this outrage.” (~27:41), you’re good to go. Otherwise you’ll need to download the subtitle file Harmy linked earlier: https://mega.nz/#!Ll03BZyY!3YEdAOXEKXJ4yj-wIfnXgWfnQmf0m5YH4i-bnlYrqSU
