unable to play certain scos

I've been able to upload and play several scos off of the scorm.com examples page with no problem, and I've also been able to play my test sco created using adobe captivate. However, when I try to upload and play my client's scos (created and published with captivate by our creative department) I get errors when I try to play them. As a test I uploaded these same packages to scorm cloud and I can play them just fine there. (that doesn't rule out the possibility that we are publishing them improperly somehow, but it does make me want to dig deeper into a possible bug with sco_node while I tweak the publish settings)

I don't get any errors when I upload them so I assume sco_node thinks it successfully parsed the manifest file. However, when I go to play the sco there don't seem to be any organizations there. In fact it looks like $node->sco_manifest is NULL

Here are the errors I get when I attempt to play the sco

I'll dig deeper on Monday but I thought I would just ask here in the off chance you saw something obvious in the errors or the manifest file (attached... I had to zip it in order to attach it due to filetype restrictions). I diffed two manifest files (one that worked and one that didn't) and I didn't see anything obvious or drastically different between the two.

Thanks!
