Framemaker 11 - subscription / serial

Hello all,

Does anyone know how/where I can get a subscription or a serial for Frame 11? I have an FM 2015 subscription already, but plenty of my clients still use FM11. I had the trial version but it's expired. The 'Buy Now' link on FM11's splash screen just leads to a 404 page, and the 'License this software' button asks me for a serial, which I don't have. Support Chat is currently closed (surprise!)
