Yep that is a known issue. Currently the playMobi plugin does not work when exporting using DirectCanvas. I wanted to get the initial version out as it works everywhere else, web, mobile web, and device, just noton device with DC enabled. I also wanted to work on some appMobi plugin additions that folks have been requesting. There's just some additional logic that I need to implement into the plugin to make it work seamlessly for both DC and non-DC games. But have no fear, DC support is on the short list for the playMobi plugin.
