Hello,
All who are facing the problem Current configured Preferred server.. not available. and are not seeing the NSE server in the list....
You would be missing a file plugin.xml that is required.. I have uploaded the file at this link... http://www.4shared.com/document/bV4qYDjP/plugin.html
Just place the file in the %APPDATA%\OptionsOracle folder and it should be working fine.
Cherio,
Praveen.
