Global really does mean global, within Max at least. Even other scripts can use variables globally declared in other scripts (in fact, this is one of the reasons why declaring global variables should be kept to an absolute minimum – especially if it has a fairly simple name that could easily be used in other scripts, like “count” or “theMesh” or something. This is, as you correctly diagnosed, the reason why it was working, then ceased to work after you closed Max).

I was wondering about that thanks for the clarification. What is the best way to have variables multiple scripts need access to?

To avoid that kind of problems i use this stencil to write scripts:
stencil.ms:
-- General comments about script, name, creation date, last modification date, author, source of inspiration authors or pages, changes log....
( --start script
--write all inside
--includes
-- local and globals variables
global mainRoll -- rollout name may be global but sure not with that name
local SourceDirectoryName_STR = undefined --your variable is local and you can initialize
--local functions
fn addProjMod lowResObj highResObjs cageOffset =
(
--blablabla
) --end fn addProjMod lowResObj highResObjs cageOffset =
--rollouts
rollout mainRoll "Unreal Multi Tool"
(
-- blabla
) --end rollout mainRoll "Unreal Multi Tool"
createDialog mainRoll 175 450
) --end script
Sure there are better ways but at least it works for simple scripts

I will make sure to use the for the future and thanks for the heads up on the use of undefined. I had tried that before but it was not working, probably because I had it set up incorrectly, but everything is coming along nicely now and I am starting to get a better and better grip on how all of this works. Here is what I have working so far in case anyone is interested.
-- Store the selected path so that we can use it / change it later on.
-- This needs to be up here or it will not allow the saving of the path. This will conflict with the other sctipt as I do n

-- Makes sure that we have only one window open at a time.
