Mark -
Last evening my portfolio of stocks and funds updated fine. However my separate portfolio that retrieves the values for the Thrift Savings Funds would not update and it won't this morning. I manually added in the closing prices for the funds since they were on the Thrift site.
The error message I received told me to check internet explorer about offline. I am using IE11 on a Win 10 desktop. When I press the retrieve button in Fund manager it shows that it has grabbed zero prices and the actual message displayed is "System error code: 2 Message: the system cannot find the file specified."
