Time Machine failure with OSStatus Error 89

Hi! I recently started experiencing issues connecting to my Airport Time Capsule (26 days ago). When I try to connect, it just spins and then gives me the error OSStatus Error 89. I've tried rebooting the device then reconnecting to the network but that doesn't seem to help. The weird part is that I can still see it connected to my AirPort Utility just fine. All systems Go there. I just cannot connect to it via my MBP via Finder or as my Time Machine disc.

I really don't want to scrub this device as it holds gigs of personal photos in addition to over a year of backups. If that is the only answer, then I HAVE to get that data off there first. I assumed there was no safer place for those pictures than my TM. I was wrong.

I appreciate any help you can provide.
