The added files are okay, that's just stuff that RTW generates for you.
The lighting, I presume you've switched out with the trivial script.
.\eb\mp game edu backup\map.rwm is supposed to be in the ignore list, sorry about that.
I don't know about the Ausculum description, but it shouldn't make any difference to starting a campaign.
The descr_strat is a different matter. I don't know how that happened, but my own installation now says it's the same checksum that you have. I'll have to update the checklist.
Edit: Now I see that a last-minute change came after I generated the checklist. Your descr_strat is fine.
Edit2: You can update the checklist when running the validation now, I've uploaded corrected files.
