AbanteCart-Error :'(

[Doina]

My site does not work or admin page, I see the same error message
      " There has been a critical error processing your request

Please check AbanteCart and webserver error logs for more details. You can check error log in the control panel if it is functional. Otherwise, refer to error log located on your web server"

I chose AbanteCard, because a friend recommended it to me as being easy for me to use,I know nothing about website Programs,
what can i do?
