Oh, I feel your pain and my blender did the same thing last month after I got it. First off and make sure the lid is on tight because some have a safety feature that won't let it run otherwise. Works like a charm once that's set.
If that's not it, try pressing the reset button if there's one on the base, sometimes they trip for no reason. And hey, if you're still stuck, maybe ask a grandkid to take a look, mine always figures out these gadgets faster than I do.
Only push once if you add real info. Say you have a higher offer but prefer them and ask if they can meet a specific number. "If you can do X total comp, I will sign today."
