Though you've not indicated a need, someone earlier had a problem so I'll pre-empt it, in case you or someone else does need it.
If you get stuck at the Act 4 to Act 5 transition, one of my earlier posts explains how to fix that, but I'll give the short version.
You'll either need to start a new save, or use the console or URM (Universal Renpy Mod) to change your sVersion variable from "demo" to "backer".
You won't have this problem if you started your save on the backer or steam versions (which are what is leaked here), though.
