The   <add key="CuteChat.DisableZipCompress" value="true" /> needs to go on line two of your web.config file immediately below the <configuration> tag.  I tried it every where else in there and would get errors.  It now works for me.  It loads slightly slower, probably to be expected I would think as it looks like we are turning off the compression when the app downloads or starts.  Below is what it should look like.
