But did you remove the sponser as said by Tony? Do that and most probably your problem will be fixed. Also, if this doesnt fix your problem post a screenshot of the error(haydn said that before).
Edit :
How to post a screenshot
Make the window you want a screenshot of the active window. Press alt+PrtScn(generally above home). Then go to paint/Photoshop(File>New) and paste(ctrl+v).
Save the picture and upload it @
