I'm trying to return the favor to the community by seeding what I've downloaded. However, when I go to seed a completed download it starts ok. But then theres a red exclamation point in front of the name and the status says, "Error: Invalid download state, try resuming." Resuming doesn't do anything. Or it says,"Error: Files missing from job. Please recheck." The file shows nothing missing. How can I fix these, and how can I prevent this from happening? Please explain clearly as I'm not as adept as some of you. Thanks much.
