Seller's attorney wants to change contract terms

[Account Closed]

I'm working on wholesaling this property, where I put down my LLC "and assigns" as the buyer. Seller and I both signed and the contract was forwarded to her attorney. The seller's attorney wrote back changing some languaages in the contract, but specifically indicated that the contract will NOT be assigned and that my LLC must close on the property.

Would this constitute a counter-offer? I can't accept the changes if I can't assign the contract--it wouldn't be wholesaling right? If I refuse to accept does this mean I have to get the seller to sign a new contract or can I proceed with the original contract as long as the seller is willing? Or should I just walk away from the deal?
