I seemed to have lost the ability to open my WAV sound files. I partly uninstalled my Creative Sound Blaster programme, so after a re-boot, reinstalled it. Could this have corrupted all my sound files? In Windows Explorer, everything is there except the extension .wav. When I double click the file, it simply reports that it is unable to open the file. Am I able to recover these files? Can someone throw some light on the problem - I have hours of music that I would not like to lose.
