Our .com server is back again for now, and so downloading has been re-enabled. Unfortunately there are still some problems with uploading files, so the new feature will have to wait a day or so. This problem was caused by the transferring of files, which made the directories on the server inaccessible for us (for writing). This will be fixed asap, which may result in another bit of downtime of a few hours. We are tired of the problems too, and hope everything's working properly again tomorrow or monday.
