What the heck happened? My YNAB 3 budget was balanced. Been using it ever since 12/2009. Now I switch to YNAB 4, open the same budget, and I'm almost $15k overbudgeted! I don't want to go back through 2 1/2 years of transactions and have to figure out what's up. I know I had this problem before when I turned on error checking, so I turned it back off. Now I can't turn it off. YNAB is suddenly useless to me. I think I'll go back to YNAB 3 and ask for a refund. This is too much of a headache.
