Hi,
I'm sorry but due to anti-bot measures, cookie login is required for mygf.com and due to that, sessions may expire earlier.
There is nothing we can do about this.
Regarding "skipped - account missing":
Add an account usage rule for this host and disable downloads without account to avoid this error:

Please keep in mind that fi your account gets disabled due to an expired-session, you will run into this issue nontheless!
Regarding "an error occured":
Please post a log that shows this exact error.
Can your reproduce this reliable e.g. doies it always happen when adding a certain URLs?
