I am running the windows 10 2017 version (R15.15) and suddenly my net worth and portfolio values are off by 92 quadrillion dollars. Unfortunately, I am not at home so restoring from a backup is not an option. I would lose far too many transactions anyway.The portfolio value view shows securities I have not held since 2010 worth "only" 35 quadrillion dollars each - trust me, I was never that rich. I have searched for transactions to try to sort this out and there are none. The associated dates for the change are in Oct 2010, but in the account (one of my IRAs), no transactions on these securities for that week exist. Any ideas on how to get out of this?
