East Coast USA alternate v2 will not load

Can anybody tell me if this mod is outdated? It won't load. It's hung up on a file called collada: camera.DAE.
Odd thing is, it loaded just fine 2 or three nights ago.

I added an additional several DL's, 368 total repo mods... but deactivated all but the one in question. Do I have to totally delete all other mods to test compatibility, or merely temp-deactivating is sufficient?

 

UPDATE:
Disregard, I figured it out.

I uninstalled it in the mods listing (hovered over green-circle-checkmark, it turned to a red-circle-x, and I clicked on it); and then reinstalled it, (clicked on blue-circle-plus-sign); and now it opens fine. I don't know what the difference would be, but I'll tell you this:

1. 2nd time around I clicked on the map in the repository menu itself to download it (as I just mentioned above), whereas before, I had gone to the selection in the in forums mod page and clicked on the either the green "Subscribe" box, or the blue "View in Game" box, to download; and maybe that/those method(s) is/were problematic. I find it hard to believe that, that alone would make a difference, but stranger things have happened.

2. When viewing it in game with the other map choices in the start menu, it no longer read "East Coast Improved", or "East Coast 0.8" (I don't recall exactly what it said); but now it reads "East Coast +". And a thumbnail displays instead of a blank square where a picture ought to have been, so that was my first clue that things were going to turn out better.

Obviously the map is older, so it's not optimized for v.0.20. It feels more like what ECU felt like in v.015 & 16; but that's exactly what I'd expect.
I wasn't going for perfection here, just options and curiosity as to what the author ('111111111' (9-ones)) did with a map I like and am so familiar with.

So at least I now know it works if I want it to.
