I received an ISQL error on my machine

Hi guys,
I received an ISQL error on my machine. It indicates that it cannot execute the statement. It says “Unable to load source control plugin”. How can I know the plugin issue. I tried those by myself but failed. Anyone having idea on these issues please help me.
Thanks in advance.
