Modem Volume,cant get it turned back on

Recently I had to uninstall my ISP login,it was corrupted,so a tech from my ISP walked me through a manual set so I could get online,the thing of it is,on the corrupted login,it gave you options to turn the modem volume off,which I did,but now I have NO volume whatsoever I tried contacting my ISP (PeoplePC )they just gave me the run around,is there ANY way I can turn the Modem volume back on?.. (I posted this somewhere else by accident I do apologize:-o )

 

This came from windows help section.
