I cleaned the registry and reinstalled the app and Inquisition came up in my library. I installed it, went to work, got home, tried running the game, and it wouldn't run. I restarted the app and the game was missing again from my library.
I repeated my registry clean again just to double-check, and when I reinstalled the app again, the game failed to show up altogether this time.
Prior to this post, I spoke to the live help service twice and neither advisors could help me. In fact, they told me to make this post. Just now I have tried speaking to another two live support people (the first of which transferred me to someone else) and they again recommended I make a post. I feel like I keep getting sent back and forth between the live support and forums. They told me they'll research it and get back to me, and I'm just hoping I won't be forever left in the dark now.
I asked about compensation and the support person told me that EA offers compensation for issues like this. Perhaps I can be given or refunded EA Play to get access to my game while this issue is sorted out. Is there someone I could talk to about this? At this rate I'm not going to get a chance to do my replay before Veilguard comes out, and I'm not about to purchase the game on a different platform when this issue doesn't stem from my end.
