NEED HELP!!! Almost every button i press makes piano noises!

Hi, i am new here so cut me some slack. recently i was going to record a song on guitar tracks just like i have done many times now. But this time when i pulled up the guitar tracks page it made a sound that sounded like a piano. And everytime i clicked the record button or anything it made the same piano sound. It has done this once before and it was because i didnt have the v-studio 20 disk in the computer but, this time it is in the computer and i am clueless of what could be the problem!!! Please HELP!
