My client is getting a Form Not Found error when she tries to open the form

Hello I have a client telling me that when she clicks on the link I sent her it says "Form Not Found" and she also sent me a screen shot of it. Could you let me know how to resolve this issues? I've sent the forms out to several clients and it's important for them to fill them out before their service. 

Thank you!
