hi, when i add a youtube videos the program ask about flash player plugin for internet explorer but it is installed and enabled, can someone help me? is there a way to use local files for videos? thanks

You can't use localised video files afaik. I'm going to attempt to work around this by turning a short movie clip into a gif and triggering the audio simultaneously. No idea about the flash issue. is it in the online or offline game browser?

i use desktop version. but thinking the problem could be this, i uploaded file on line and there's only a white box without anything inside

Is it possible to post your game here? That might enable us to solve it easier (or at all).

This is another issue that can probably be solved with HTML 5. I'll try and upload a demo over the weekend.
