Hey, sorry for the late reply. You should be able to rebuild and it should work just fine. Otherwise you could install the previous engine version (it was made in 5.6) and migrate from there. Will update the project to 5.7 soon!
I don't know why, it keeps throwing errors, surely a problem on my side with ver 5.6.1 (buggiest version ever btw). I'll just wait your 5.7 build.:)
