Funny you should ask. I just got it resolved this instant.
Initially they told me that:
We did not patch your server for long time. And also, you never had permission in C:\Windows\system32\inetsrv\config in shared hosting.
But then he wrote back:
I simply tried to turn on detailed error from your web.config. Seems your site works fine now after initialization.
And, it works now perfectly.
Thanks for checking.
