Synch Rules between Computers

Hi all,
I've Hazel installed on my desktop and laptop computer. Special folder rules are synched via Dropbox cloud service. Both machines have V 5.1.1. installed. When trying to synch a folder on my laptop, I get the following error message: "Could not sync rules - Rules are from a later version of Hazel". When trying to "check for updates" on my laptop, nothing happens (so, no window telling me there is or there is no update available), except that the "check for updates" menu items gets grayed out...
Any idea on what's happening here or how to solve this?
Thanks, Tom
