ya, looks like your zk_keys.lua is corrupted.
see infolog line
[f=0000000] Error: Lua LoadCode pcall error
0, luaui.lua, error
2, LuaUI/cawidgets.lua, error = 3, LuaUI/Configs/zk_keys.lua, [string "LuaUI/Configs/zk_keys.lua"]:61: '}' expected (to close '{' at line 2) near '{'
follow the instructions in the thread i posted above, look zk_keys.lua, line 61 and fix the file.
