Tried
WinCDEmu ver. 3.6, and it was
RIDICULOUSLY easy to use, and it worked!!!
I guess that 7zip just doesn't have "the stuff" to get the job done when running the iso image file.
Can't wait till tonight when I can finally give the latest build a good run!

By the way, I know that this may seem like a newbie question (especially since I've played this game SO many times), but I saw a video somewhere a LONG time ago that showed
how one can "link" multiple orders to one squad mate so that one doesn't have to "babysit" every single little action they take. I can't find this video any longer, and I can't recall what the name of the function was nor the key that it was assigned to. I think that it was called something like "Record," but if it is that key that links actions together, how does one use it?
Thanks in advance!
