That doesn't work anymore (figuratively)
Let's say someone used to give you the googley eyes or whatever to get their way around you, and you wanted to say "It's no use, that doesn't work anymore". Would you say "Eso ya no sirve".? Gracias.
The accepted answer is incorrect, please undelete.
Ya no te funciona (funcionará)
I had to clear my head on this -- and it came to me that I wanted to use the word "nada" here.
So here is my humble attempt "Eso no sirve de nada". What do you think?
