Yes unfortunately ... back then LW Pro only lasted for 6 months of support & updates. 2 years ago they brought in a 12 month option & since then occasionally offering other cheap no support Pro versions. Last I saw LW dropped the 6 month option a week ago.

LW 4.16 is quite a good version, its advantages over LW 4.9 include being able to connect to the entire network, whereas LW 4.18 & LW 5 will not allow versions older than 4.14 to connect to them.

In some cases despite using LW Basic you might occasionally be able to connect as turbo mode but that may depend on the network at the time & your set up, etc.
