@ Jacky:
Thanks for trying to help me resolve the issue not cleared to you or anyone I suppose. From the beginning the error message says: " “One or more blueprints has an unresolved compiler error, are you sure you want to Play in Editor? MyCharacter”. Which means when after you build your level, the “default Player” will not work, no movement. something happened as described (not described clearly) withing the “Component Tab” and appeared not recoverable regardless what I try to do. I asked to help me reset the issue back to default. At any rate I did correct it the old fashion way. Thanks a lot Jacky.
