After a server crash yesterday (power/UPS failure), I restarted OG and got a message "MainMenu.fp5" is damaged and cannot be opened. Use the recover command to recover the file." Did that... then when starting up could not open Invoices_.fp5, LineItems_.fp5 and Payments_.fp5. Did a recovery on those files. OG opened, but a few things were goofy - the customers who had been invoiced for the day and had payments entered had their expiration date advanced as if the invoice had been closed, but there were only a few invoices and no payments. I manually entered those invoices and payments and adjusted the expiration dates to what they should be and thought all was fine, but after OG was shutdown and started up, now I get "Select the file you wish to recover". Here's my question (stupid and embarrassing) - my backup is several days old. If I load the backup files, can I then manually enter the invoices that are missing using the invoice number that was originally generated? I'm using invoice numbers based on date. For example, my backup is from 6/16. So if I load that, then go to Generate Invoices, the invoice numbers will be 080624-xxx and I want them to be 080617-xxx. Will it "hurt" anything to change the invoice number and date to what it originally was instead of leaving as the assigned number and date. For credit card customers it wouldn't matter since they never see it, but other invoices are emailed. Thanks for any help.
