Part of the problem is I never expected this to become as large and used as it is. There was/is no error checking on the current pages to ensure all three files are uploaded and that the filenames all match, etc. I made it quick and dirty so it looks for the ai and eps file based on the name of the jpg file. If any of the files fail to upload because of timeouts or errors it doesn't know it and still offers the files for download.
In this case, the jpg was named dragons-lair.jpg, the ai file was named dragons lair.ai, (notice the space instead of a dash) and there is no eps file. The ai file is available now.
Look for further answers in the thread I'm going to start in a little while on the vector library itself.
