When I was going to test an issue reported in the forum about SCORMs I got an error downloading a package. I investigated a bit and I found 2 things:

1. We're detecting a wrong extension from the path. The detected extension is "0 introduction oms00 rev00 mec07_c36ad382c124d598909ea7c7b4ca0f0e".
2. The first time you download the SCORM it fails because it doesn't find the ZIP file. If I retry to open the SCORM it works, but if I retry to prefetch the SCORM it still fails.

Maybe both things are related.
