Also to note, I do not have the dev kit on my “d” drive. Thank you.
I reverted back to an earlier back-up and it seems to be stable. Wondering. I wish to replace the background movie in the mainmenu_ui and previously I tried with just a picture, do I need to add a panel and then a picture inside? Or how would I go about doing this? Thank you 
whatever you do with UI, make sure the parent class of your UI widget is “PrimalUI” or it will crash no matter what.
