Downgrading Timecapsule firmware results in error -9
I'm using airport utility 6.1 on Windows 7 and I wanted to downgrade to an earlier firmware 7.6 or 7.5.2. However, everytime I tried to upload the firmware, the airport utility reports and error -9 saying that I might not be connected to the time capsule. Has anyone every experienced this or have a solution to it? Many thanks!
