Hi I am trying to upload a podcast in a new channel. but evrytime I click upload -> new item I get this error :

Security Exception

Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: The source was not found, but some or all event logs could not be searched.  Inaccessible logs: Security.

 

can anyone please let me know why I am getting this error. I am logged in as administrator and have full access. Also I had uploaded one podcast a week back in the same channel created by me.

Is it that some security settings have been changed since then?
