Residential contract for sale and purchase

[Gin Dillard]

I'm selling my house and my sales agreement contract with my buyer has expired. Both parties have agreed to move on but my Broker says I need a release from them because theirs was a VA loan. Do I have to get this before marketing my property and/or accepting a sales contract with another buyer? What are the repercussions if they refuse to give it to me & I sell to someone else?
