issue with my computer and it messed up something

SUGGESTED

I was in the middle of entering the credit card and something went wrong with my computer and it crashed. By the time I restarted and got back in I saw the batch that I was entering was still there but it was at zero dollars. I started the process of reentering the invoices to transfer over and its telling me that this invoice is being paid. 

Any ideas on how to fix this? I already tried deleting the batch and creating a new one but the system still thinks the invoice is being paid. I'm stuck on this and would appreciate any help. 

Thanks
