I followed everything up to that point and confirmed that everything was patched and compatible. I tried with only one file and it still did not show up. All of these mods were working months ago the last time I played but not a single .package file shows up now.
I of course understand the framework because they were working fine the last time I played. Items I purchased from the online store or downloaded via the installer do show up, but just those. I'm really quite stumped and need some help, particularly because the next step in that help section is missing.
Okay, I knew I shouldn't have posted but I was at the end of my tether.
I just went ahead and installed the pre-made framework offered on the wiki and the Resource.cfg file had a lot more specified in it... I think that must have been the problem even though the last time I had problems with Custom Content I replaced it with a better one, which was that one. It appears they are always being updated and I don't know about it...
So, things are working now and I am sorry for posting ahead of time because things were so readily resolved. My apologies.
