Please help me fix/re-link my Oberlo app back to my Active Shopify store so that I can fulfill order

Hello support

I can't fulfill orders by using Oberlo. I have unfulfilled order since April. When I click "Fulfill by Oberlo" it took me back to my unactive store link.  Please do help me re-link Oberlo to my existing store.  I download Oberlo App in my store.  If I undo it, will all my uploaded products gone???

Please advise asap!

Thanks
