i recieved this issue while trying to open an audio file(s).
Windows Media Player cannot access the file. The file might be in use, you might not have access to the computer where the file is stored or your proxy settings might not be correct.
this happens after i access regedit.exe to add permissions on HKEY_CLASSES_ROOT, HKEY_LOCAL_MACHINE, HKEY_USERS to fix application issue on my win8.1 that cant be opened.
this happens for every single audio files i had. and this error take effect to video files too, i can play video or movie with Gom media player, but without any sounds out. also with game software, it run okay, but without sound.
i checked my sound setting with clicking the sound icon on the right bottom of taskbar, but its good. the problem is with the audio files i think. can you help me to solve this? thankyou
