I had a working Flirc configuration based on a (FL-09028, original Gen1?) USB Flirc dongle purchased in 2014 that had been successfully programmed using the Flirc GUI v1.3.6 (don't know what firmware that would represent) and running under MacOS 10.9.5 on a Mac Mini used as an HTPC.
Had not done any Flirc reprogramming since 2015 until this week when I got my new Harmony Remote and launched Flirc to do some updates and testing. Unfortunately agreed to the Update dialog and now Flirc GUI v3.8 crashes on launch. Crash log shows Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

Amazingly, Flirc remote functionality seems to still be intact!
BUT, after recovering my original Flirc GUI v1.3.6, when running it says the dongle is at v3.8 but there is no other functionality to the GUI. Flirc dongle icon shows "Disconnected" and app is very flaky, usually requiring a Force-Quit.
Really hoping I can get this running again without losing all my remote programming or bricking the dongle. Is there an incremental upgrade path I can take with intermediate versions of Flirc GUI without going straight to 3.8?
Any help greatly appreciated!
