I do a local back up to a flash drive everyday.  All of a sudden, today, it said it couldn't because there was some problems with some data.  Said I needed to rebuild.  I did and stated it couldn't fix all and were 4 it couldn't.  Those 4 things made no sense.  3 were about bank feeds, of which I don't use with quickbooks and the other with one of my accounts and I don't understand.  I changed the flash drive, same thing and then I closed out and rebooted my computer and same thing.  What the heck is up all of a sudden?  Help
