Thanks for your quick responses, but I thinks it�s not related with any of your given solutions:
Kyatric: I think is not related with that bug cuz I�m able to test the game in preview mode directly from Construct (I�ve tested it in Chrome, Firefox and Ie, and no problem with any of them). The problem comes when I use the exporting tool.
Sargas: No man. I�ve tried uploading it to my Dropbox, and didn�t work. And now, it�s not on my computer (see the link in my first post), it�s uploaded in my website�s FTP.
I�ts curious that, if I try to open the file in my local machine (before uploading the exported version) it returns the alert that tells it�s not going to work properly until I upload it somewhere, so that is correct.
But after uploading it, I have no good response.
Thanks for your tips anyway :)
