Language (and Interface) Changed?

I hope I put this in the right forum.

Yesterday, I found my Creative Cloud had signed me out. I'd forgotten my password and after a few tries I figured maybe I'd used a different e-mail. (My work e-mail instead of my personal e-mail). It immediately signed me in with the first password I tried, huzzah I thought!

But now everything was trial period stuff, even though I'd just signed on for the Black Friday action year-long subscription the day before.

I opened Illustrator, and everything seemed fine - despite the trial period anyways. I quickly finished some work and figured it was a problem for tomorrow.

I found that I'd signed in with the wrong account, and that'd been why everything was marked with the trial period. After some googeling, I managed to sign out of that account and back in to my actual account (maybe it automatically created a new account by me signing in?) but...

Now my Illustrator is in English instead of my preferred Dutch, which I marked on my account and double-checked (it's still there) and my entire re-arranging of the interface has become undone! In fact, my workspace doesn't seem to exist from the drop-down menu anymore (like "Essentials" and "Automation").

Photoshop and InDesign remain in Dutch with the changes made to the interface intact. I didn't open these while I was on the other account.

Any idea how to fix this? I'd like for my Illustrator to be in Dutch again in the very least as I'm confident I can recreate the workspace, but have no idea how to change it as I've already checked and my preferred language is still Dutch. Any ideas welcome!
