Mick - thanks for the reply. I'm afraid you're right.
I have a Lutron system that was installed over 10 years ago, and the processor died. I was able to buy a replacement processor, but the firmware on it won't support any HWI version earlier than 1.49, and my project was done in 1.32.
I have since upgraded the HWI software to the latest version I have (1.60 BETA), and uploaded that OS and my project to the replacement processor. It's working ALMOST correctly - but some of the circuits connected to WPM's are flaky. I thought downgrading back to 1.32 might help but as you say I don't think it's doable...
