Can't unity running on my web site still

I am having trouble getting unity to run on my web site. It runs fine locally. I contacted my web host company and they set up a mime type for the unity3d file type as was suggested in a previous post. The setting I gave them were

application/vnd.unity

And the file extension for unity webplayer files is:

.unity3d

So, if you're editing htaccess files on your server, you need to add this:

AddType application/vnd.unity unity3d

They are using an apache server.

It's still not working after they set up the mime type. They have not come across unity before so they have no idea what to do now. Has anybody any suggestions what they should do?

I had the same problem, what error the unity web player displays? After setting the mime settings still it wasn't fixed. They were hosting my site in an old windows server and when they migrated it to a new Linux one everything was fine. This is what they told me . I spend a week in back and forward emails to be honest and I couldn't figure out what was wrong with the windows server. I think it might have been some timeout setting, or the fact that it was a shared second class server. Unity hasn't got any information about specifications so someone like you and me can forward to hosting providers. I would really appreciate that.

Just in case though, check that the file is uploaded correctly, delete it and upload it again.I made a tiny test file with a few boxes so i can check quickly. And check if your ftp client chooses binary for the .unity3d file, some free ones are messing it up. filezilla for windows is working fine.
