Servo Analyzer 1.0.0.0 (Third release) and Firmware

I recently tried to update my firmware to 2.2.1.25 to try and bring our system more in line with Delta Tau's production release, but after the install, the Servo Analyzer no longer works reporting check firmware version. Questions: Is there a newer release of the Servo Analyzer that works with this and newer versions of firmware? Assuming the answer is no, what is the value of the annual maintenance fee we pay for the Servo Analyzer, if no new development is being done on it? Finally what is the most recent version of firmware that works with the Servo Analyzer?
