9.0.2.421 json
If you updated to the latest patch Captivate patch 9.0.2.421, and you upload your file to a website and it no longer plays... tit maybe a json issues. Here's what I discovered.
Inside your web.config you have to include
<staticContent>
<remove fileExtension=".json" />
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
Inside the staticContent tag you may have more MIME definitions, you should leave them existing as they are.
Hope this helps!
