Vista - DSP Group TrueSpeech Audio Codec

Hi I recently installed vista 64bit Ultimate and I tried to use ventrilo however it kept giving me the error:

Failed to get encoder for specified Codec.

Unable to initialize outbound codec (DSP Group TrueSpeech - 8 KHz, 16 bit): Unable to find the specified codec.

I have TrueSpeech Installed (says so on WMP) However it doesn't initialize.

This is what it says to do on the Vent site.

Q: Unable to initialize the codec. CODE = -10

-10 means the codec is found but is marked as disabled.

Control panel
Sound and multimedia
Hardware
Double click "Audio Codec"
Double click on Microsoft GSM 6.10
Click on "Use this audio codec"
Press OK.

Since I've just switched to vista I find it hard to navigate around the control panel since its so much different than XP. Can someone translate those XP instructions into Vista, or tell me how to initialize the codec.

Thanks.

can you start ventrilo, or does it just end itself when you get that message?

Yes i can start vent. When i join a channel i get a pop up box with that error.

you need to ask the people whos channel your connecting to to change the default codec to GSM or speex, however, you can test your codecs with the setup option on the right of ventrilo.
however i may have found a fix, just checking through it now.
ok, you can download the codec again, some issues can restrict access to the vent one, so if you install the klite codec pack from here> k-lite codec Pack full, this pack does include DSP Group TrueSpeech audio codec 1.1.1.5, restart your system and try the codec in ventrilo, should work.

I already have it installed, and The test does not work, it says it cannot be initlized. I'll see if i can get my friend to change the codec.
