so while i had all the same error with the 30005 / failed with 32... and i tried a lot of different solutions which people wrote, i found my solution was an easy thing to solve. Because the problem seem to accure in random time, and get solved by itself. I recognized it is the anti-virus passive scans.
I have Kaspersky internet security.
This (and probably other anti-virus tools) do a "rootkit scan" from time to time. This may happen after you started your PC or at different other random times.
You can easy find out if it does so, when you mouse-over at your kaspersky-icon on your windows-bar at bottom-right. If it does the rootkit-scan, it shows in the mouse-over on which %-status it is. So when this is over.... i can start the game without the problem (30005 / 32).
See picture-attachments.
i am sure, there are other anti-virus or firewall tools that do the same or similiar scans from time to time.
I would not turn them off, but you may have a look if theres something running passive, which may be finished after (for me) around 1-2 min.
