Wont burn dvds anymore



Ive been burning dvds for about a month now and ive been using dvd shrink and it has worked fine and now all of a sudden it wont burn my dvds anymore and if I try to copy pics or music or anything else i get this message “Windows encountered a problem when trying to copy this file. What do you want windows to do.” it will still let me copy dvds to my harddrive it just wont let me burn them and when I open dvd shrink to burn them it just freezes so any help would be appreciated! Thanks!!!
