Resolved Cannot open Outlook

New computer. Data files from old computer were in a file called "From Old Computer." Everything was working fine, including Outlook, until this evening when I decided to move everything out of "From Old Computer" to Documents. Wrong thing to do. Now I get " C:\Users\Alice\Documents\From Old Computer\aliceandtj@comcast.net.pst cannot be found. " I tried to reverse what I did, but I've lost my way.
Please, someone, help me.

Response to Arnie

Thank you for responding, Arnie. That's what I did last night after I wrote for help. Couldn't wait. It was so frustrating. Anyway, I found more than one pst file and evidently imported the wrong one. I can open and use Outlook now, but there are no contacts, no extra folders, etc., and gazillion emails that I got rid of a long time ago.
Do I just try another pst file? Do I delete the first pst file first?

 

Thank you

Thanks, Steve. I did import another pst file. Now I have two identical accounts, neither of them right. I give up. I'll pay someone to get it fixed.

 

Got Outlook fixed

Thank you, Arnie and Steve. I finally got Outlook fixed and didn't have to pay someone to do it. Thanks for your suggestions.
