tried it again? there are many reasons what caused this error, just try it again
I have the same problem with Greenfoot version 2.1.2. If you are not upgraded to Greenfoot version 2.2.0 or better, I would suggest you do so.
This may be a bug on the site, not allowing older version(s) (at least 2.1.2) to be able to upload scenarios properly.
Thank you, i was about to do it before you repply.
Could you all try again, there was a bug on the server that was breaking uploads from older versions. But note that upgrading to the latest version of Greenfoot is always advised.
I upgraded successfulley and share my game yesterday. Do i repply correctly to you?
Thank you, glad it worked for you! :)
