i don't follow what you mean...

currently i have 4.16.1 installed. is this not the most recent?

i've been using LW for about 6 months, since around 4.10.x or so, but it is only very recently i have had a problem with it. i still get 5 green bars, but i also get the damn firewall.

i don't know why i started to get the firewall, i think there is something wrong with LW.

are you suggesting i uninstall 4.16.1, delete any traces of it from program files, and reinstall to an earlier version?
