[Plugin: Uploadify Integration] Not working with 3.3.1? Or perhaps multisite?

I recently updated to 3.3.1 as well as switched to multisite. Not sure which one cause the problem, but this plugin is not working anymore.

Now it goes through the full upload process, but then instead of listing the file below, once it’s completed, it just shows “-1” in text and that’s all. Any chance there’s a fix coming?
