Update
We initially thought there was a problem with the linux server, but it would now appear that the error was a false positive; I'm very happy to report that the linux server should work fine! To clarify: The Linux server package is exactly the same as the one that was previously uploaded & then removed from the site, so if you already have it, you don't need to re-download.
