That was one of the suggestions I had read about earlier but hitting the manual reset prior to upload made no difference.
Hitting and releasing the reset switch prior to hitting upload is probably not the correct timing. Usually I hold down the reset switch and release it only when I see the size of the sketch being reported at the completion of compiling the sketch but prior to the uploading task. It's a bit tricky but can be learned.
