One Step Update hanging up on Quotes and Investment Information

For the last two days, I have had an issue with being unable to update my Quicken accounts. I ran the latest update which came today, turned off the computer and then reset each account. All account updates are able to be run successfully UNLESS I turn on Quotes and Investment Information. With that clicked on to update, the system hangs up completely and Task Manager shows me a "not responding" error. I tried to validate the file and that also hung up at validating stock splits. This is extraordinarily frustrating. Thank you.
