hi, just a note on the log, have you deleted the 2DSideScrollerExampleMap? from the log it looks like you created the c++ project using the 2dsidescroller sample template, deleted and my guess is that you havent changed the settings on Project settings.
also, you got a huge external reference errors and “empty engine version”. my guess is that you have moved your project to a different folder (or has been shared) and the project files are broken. have you tried the delete Intermediate/Saved/Binaries folder, change project folder name and regenerated the project files method? (to be followed by the proper recompile)
