[Info] Sims 4 - Download & Installation & Startup issues

I also had issues with the preload, however I have now resolved them.

My issue was, it said "Processing" and "We have billed you for your order, but some items are undelivered." However the preload was not available in my Origin client, no matter how much I logged out and in and reloaded my games.

It turns out that the order had been made on a card that was now expired. So even though the card had been billed a while ago, the order could not complete to the stage where preload was available because the card was now expired.  

There was a link on my order that said something like "Modify or Cancel Order" (it was in French so I'm not sure of the exact English words... living in France forces me to see everything in French on Origin...). So I clicked that and noticed it was still referring to my expired card.

So I changed that to my active card and accepted the change. A few minutes later the preload became available in Origin and I got a "You can now preload" email.

Good luck to anyone suffering the same issue. :-) Happy Simming!
