Forums mIRC Help Loss of sound in mIRC?

Hello folks,

First time here, I tried to search the forum relating to the problem that I am currently having but to no avail. But if by chance I made a mistake, I apologise for not checking further within the forum.

The problem:

I have lost complete sound capability in mIRC? It used to make a sound when connecting to an IRC server, private chat popup, chat activity,etc.

I checked the sound options showing a tick on enable sounds, but each sound for connect, disconnect, chat popup, etc, are showing no sound. If I press the button, the other choice is beep?

I can confirm my speakers and sound capability on my PC is working ok. I am using Vista64 Sp2. It was funny that I had Sp1 and after Sp2, my sound in mIRC is gone?

I discovered a hidden folder within Vista called Roaming/mIRC sound(not the exact full path)which is completely empty? I even tried to uninstall/reinstall mIRC but still no avail.

Anyone has ideas on how to restore sound to its original form?

Thank you.
