Just to clarify - the error doesn't appear when previewing, for instance, one of the built-in examples, but only when previewing your own bomberman .capx?
Are you using any non-standard plugins?
If not, then the .capx will be necessary probably.
Unfortunately, the forum attachments are currently disabled due to them being foobar'd :/
Do you have a Dropbox account you could use? Or googledrive, etc....?
