Open World Demo Collection Unavailable Already Owned?

I had to reset my computer mid download, and now its not in my library and it says its unavailable to download! Help!

I don’t know what the problem is. but try not to download OpenWorldDemo Collection if you don’t have a very powerful computer otherwise that will be useless.
I couldn’t use that with 16 gig of RAM and GTX 780 and 4790k 4.00 GHz

go to this address C:\Program Files (x86)\Epic Games\Launcher\VaultCache

and delete that if exists

and restart your launcher

I was able to open it on a laptop with a i7 2.4 ghz and 8gb RAM nvidia 750m. On the really large demos like open world and infiltrator you need to let it run for a long time. It may look like it’s stuck but trust me eventually it will load. Took me about 45min to an hour
