Why can i not add a new link to the main menu? I cannot for the life of me figure why i cannot add a new link to the main menu?!

the error i get reads 

'The path 'events' is either invalid or you do not have access to it.'


i have tried numerous work arounds, tricks, checked permission, menu modules, everything i can think of but i cannot understand why. 

am clueless, does anyone here know?
Go to Modules list /admin/modules and make sure the Path module is enabled.
