Guys, if you've just updated & can't connect - try the fix of deleting LW's preferences folder. See this thread for more info & remember that you may have 2 folders in different locations, if you've used older versions of LW in the past: If LW Will Not Connect

If a connection problem suddenly happens after updat1ng/upgrading LW then deleting the prefs folder is very often the fix.

If not then try all of the other fixes in that thread. Please tell us if you've had problems/concerns with any of the fixes.

Let us know if none of them work.
