Hi Yum and thanks for your reply.,
This issue has been happening for about 6 months. It does not happen to any new files I delete. It is always the same 7 filenames that keep reappearing after I delete them. I delete them by clicking the small wrench tool icon that has the Delete Files option. After I select the broken linked files, I click the yellow Delete button which asks me to confirm the delete. I click Delete and they all disappear. After I exit and restart SkyBox VR they all reappear again.
I sent you an email (subject SkyBox VR Broken File Links) with screenshots. Please let me know if you need anything else.
