I find that something in dspy is broken and doesn't delete the directories anymore (in Win2K anyway), so I just delete the entire directories. When d2ol starts up again, it redownloads the problem candidate. Usually, the corruption is due to part of the file not being downloaded, so redownloading it is fine 🙂 Remember to shut down the client before you do the alt-f or client that are in the process of being downloaded will be identified as corrupt.
