[Plugin: WordPress Download Monitor] How to

Good afternoon

i have been testing this plugin but i cant figure it out to work. the documentation by the author is not to clear for people like me that are not geeks

i just installed the plugin, and i added an existing file which gave me download id of 1.

then i went to a post and placed this on the post but it didnt give me a link

[download=1 format=1 autop=false]

what am i doin wrong? Please its kind urgent

Thanks
