Reinstall purchased MS Apps from Store on new computer

No, I tried that and they are not there. I'm beginning to wonder if I have two MS accounts...I own a company and have one, but I'm wondering if the purchased may have been through another account. Also noticed when I look at my devices, this NEW Surface Book 2 is not listed. All seems odd to me. 

Is there an easy way to know if I do have two accounts? I know that with Skype's purchase I had a login there...trying to sync them all if I can into one. Same email address though?? 

I appreciate any additional thoughts. 

So I tried that too. But what's odd is that I can see the Premium purchase in my orders in this account. It's there...showing that I bought it in March of this year. But it is not in the account. I have a snip of the purchase...

We may be getting somewhere. Here is what I think has happened so far.

1)  When I set up this new computer, because I own the company, I set it as a work/school since we subscribe to Office 365 and it remembered all those setting. Email address is my usual address. For the sake of this explanation, my picture is in black suit, brown glasses. 

2)  I think the email address for "microsoft" is the same email but was perhaps with a different PW. May also have been my XBox Live login. I followed the advice here and logged out of the store. When I tried to log back in I said "forgot password" and reset it. When I logged in with new PW, my picture was , for the sake of this explanation, different from #1 above, in purple dress.  I found lots more in "my library" in the store, but still not the ones I purchased. That purchase, as noted in an earlier part of this thread, was noted in the original login, noted in #1 above. 

3)  When I login to my MSN home page, I notice that I have the same pic with the purple dress, as #2 above. I also think this was my "real Skype" login, before I stopped using it. (I now mostly use Skype for business as part of my company, or Microsoft Teams for companies I consult for)

4)  When I login to my admin panel for Office 365, I see the same picture as #1 above, my Office 365 login where my name is my professional name Kathy Mills Chang, MCS-P, CCPC, CCCA. 

5)  In this store account (purple dress) "my library" I have a huge number of apps and games, mostly free, that I recognize from my existing (one I just am replacing now) Surface Book and even my previous computer with Windows 10 and even an older one with Windows 8. I went into purchased and found the Microsoft Casual Games in question...and it was able to sync to my current account! Yay!

In closing, I think now it makes sense that I have had two MS accounts, same email address...one through Office 365 and one for all other MS products. I think I've now sorted out which PW goes with which, and how they are aligned. I will try to take it from here, but I thank you for helping this old granny with getting organized here.
