Hi George! Possibly... you'd have to tell me a few things:
I see that you posted using Ecency, so that shouldn't be an issue. I also see that you got refunded 150 points, and that's the minimum, so that's not a problem. How long after the post did you try to make the Boost? Sometimes Boosting too long after the post was made can prevent it from being accepted.
