Need help moving to new browser

I recently upgraded to Windows 10, which required me to reinstall Brave and other software, including Metamask. After entering my 12 words, I notice I have a different wallet address in Metamask and I have no assets in it currently. What can I do to get back my old address on my new browser? In case it helps, I still have whatever files Brave made in my windows.old folder. I don’t think I had more than one Account in my old Metamask, but if that’s the cause for the error, can I recover that account somehow?

Update: managed to rollback to Win7, export private key and use that to reconnect my Metamask on Win10.
