It looks the exact same as 1.4.2 to me. For example, you said
- Change this: local dir = "addons/MakeFriends/"
- To this: local dir = "lua/MakeFriends/"
if we want to move it to a different directory, but start.lua has
local dir = "MakeFriends/"
as the default.

And yeah, I meant the "attempt to index field `?'(a nil value)" lua error.

Aleksey, that's v1.4.2. Unless I fail at winzip. Checking that now.

The --declare("MakeFriends", {}) has been in there since v1.3.whatever.

Edit: Well, it's 1.4.2 whether or not I fail at winzip. But the problem might be arising because I fail at winzip. Or accidentally overwrote 1.4.3 with 1.4.2.

Or possibly you need to clear your cache.

Edit: Also in v1.4.3, start.lua has been renamed to main.lua and the former main.lua renamed to mf.lua

Edit2: Apparently v1.4.3 never really got released because I fail at FTP. Out now.
