4.9.33 is the latest version (the Pro version is also available from your Pro page), but I think you have found a different problem related to the normal "sleep" behaviour.

I read that the developers have noted that in some unknown cases, LW is going past the sleep stage and disconnecting. The devs are trying to get more info about what may be happening here.

Perhaps you can help: For example, some ISP's change the IP number daily. LW is supposed to recover from this situation. Can you find out how often your ISP changes your IP?

Thanks
