Mark,
I'm having problems updating investments' old prices today. I tried using Yohoo (historical), Google (historical), and Quandl (historical) tserver o update old prices but I got the same error message ' could not update any investment. I'm using:
Main Program: 2016.14.7
Quote Module: 496
Transaction Module: 218
Updating today's price using Yahoo quote server appears to be working fine. Would you please look into this problem? Thanks in advance.
