Does work 7.5.0 client with 7.4.1 SBS ?

[mikrotom]

I just upgraded FW in my Squeezebox Duet remote controller to version 7.5.0 r8673 and are unable to connect to my library on SqueezeBox server wich runs on Synology DS209+ (which is 7.4.1 - r28947). I tried restart DiskStation, even reset Squeezebox player. Nothing helps. Some suggestions? If my assumption is all right, is there any way to downgrade FW on Squeezebox Duet?

If you reinstall 7.4, the controller will prompt you to "update"
