I've been using FM v12.0 without any problems. Tonight I decided to update to v12.6 and after installing on top of v 12.0 I can no longer download transactions from Fidelity Investments.
I also tried downloading from Merrill Edge and it failed the first couple of tries with a different error message, and later it started working. Downloading from Sharebuilder worked consistantly.
I did a backup of v12.0 before the install. I restored that backup into v12.6 but it didn't help.
Retrieving Yahoo historical prices worked.
