I'd suggest adding new litterbox in the room where she is currently peeing to give her two options: basement and this one. Could be that, as she is getting older, this will be more of an issue.
I also agree with the PP who said that the rugs could still smell to her. Why don't you remove the rugs for a while and see what happens?
