I tried the demo before hand with no issues. After activating KLAX V2, I noticed P3D default runway textures were showing
I'm sorry, but this is plain not possible. Do you recall having download something else to activate the scenery ? Surely no. The scenery is exactly ( 100%, bit-by-bit IDENTICAL ) regardless if it's active or not. Activating the won't change a SINGLE BIT in the scenery itself so, it's not technically possible that a scenery would run any different in Trial version compared to when it's being activated.
So, the only possible options to explain this are:
- The problem was already there in the Trial, but you haven't noticed it
OR
- You installed something else in the meantime which caused it.
I've tried uninstall / reinstall of everything numerous times. I've also cleaned appdata, local, roaming, reg with each install. I've downloaded the current addon manager... I've searched the forums extensively. I've really spent way too much time trying to diagnose this problem for $38...
Well, of course you don't have to do this "for 38$", since the Trial is there for the precise reason to allow you to test if the scenery doesn't conflict with something else in your installation BEFORE purchasing it. That's the whole point of having a Trial to begin with. As I've said, a change in appearance before/after the Activation is not technically possible.
Not to mention all the work I will have to do to reinstall all of the other addons again.
Who told you you have to reinstall all the other add-ons again. In fact, there wasn't any need to uninstall/reinstall the scenery itself so, all the time you lost, it's because you are assuming the scenery has a problem, when in fact the most likely cause it's a conflict caused by something else.
If the scenery had this problem, we would have a lots of reports of it by now, but instead, the problem as you are reporting here, which if I understand correctly is:
"FSDT textures showing up for 1 second, then default appears"
Has never reported before so, it's clearly a problem specific for you issue.
So, now that we clarified the scenery is not the problem, we can start troubleshooting what the real issue might be. First, what do you mean with "FSDT textures" ?
JUST the runway textures, as it looked like from the start of your message, or all the ground textures or, maybe, all the airports textures ? If it's just runway textures from default, the problem is clearly another scenery AFCAD in conflict. If it's not, then please clarify exactly what elements from default scenery you are seeing.
