Timecapsule - No Longer Have Pemission

My time capsule seems to be working fine. I can see it if I use Disk Utility.

But if I try to open it or backup to it I get an error message that says I don't have the permission to do that.
I did a "get info" and tried to change the permission back to me. It says "custom" and whenever I change it to Read Write it goes back to custom.

I have the correct password but if I try to make it the backup in Time Machine it then says I don't have the permissions.

Any ideas?
