Construct 2 Game on Newgrounds

Hey Guys, I made a game with Construct 2 and would like to publish it on Newgrounds. But it seems to be buggy...

Some of my sprites don't show right (they appear as a grey box). And when I use Firefox as browser the change between two layouts is not working...

This is only happening with the Upload on Newgrounds. On my own Webserver the game is running normally...

Is this a common problem or did I something wrong?

This is the game.

-> On Newgrounds the street and the bears are shown as grey boxes...

Can anyone help me please?

Can nobody help me? :(

We would need the link to Newsgrounds or even the capx to help you.

Maybe posting it to Scirra first ad then embedding it could work. I'm not really "the authority" on Newgrounds, so maybe the above poster knows more on the deal.

Sorry for not answering earlier...

I totally forgot about this post :S

I found the problem!

I was so stupid to use german special characters (ä,ö,ü,ß) as names for sprites. Those characters are not available in the ASCII - Table. Thats why some sprites could not be loaded...
