Dont worry, dear sister, we have doing pooja for Lord Sathyanarayana for almost twelve years now, you can keep and pray at your pooja mandhir... If there is anything specific in what he said then please analyse or share it here for us to understand.. Best wishes...
I am of the opinion that, If you focus your thoughts on the divinity of Satyanarayana without disturbance, you may have Satyanarayana photo at home and do puja regularly.
