Windows 7 upgrade, now mic doesn't work (soundcard problem)

[demised]

I previously had windows vista installed on my computer and just the other day reformated and installed windows 7 64bit. Before reformating and installed win7 my computer worked fine.

Now after the upgrade to win7 i am having problems with my sound card. I have a Creative Worlds - Sound Blaster X-fi XtremeGamer sound card.

My sound works fine, i can watch movies, listen to music play games, my sound comes in fine. When i use skype or ventrilo to talk, my microphone doesnt work and a message comes up that says Cant access your sound card. On vent it says "Unable to activate DirectSound for selected device. DirectSoundCaptureCreate failed. HR=DSERR_NODRIVER. No sound driver is available for use"

The first thing that came to my mind was installing the drivers. I downloaded the drivers from the creative worldwide website for my sound card, and from dell.com for my model computer. When i try to install them, it says "Device object not present, please restart and then run setup"

So i thought ok, my computer isnt recognizing my sound card, so i downloaded a identification model off the creative worldwide website for my sound card. Then when i try to run that, it says "Your version of Windows Operating System is not supported by this product. Please upgrade to windows 7 or later versions before trying to install".

Anyone have this problem or have any suggestion of what to do?

What model Dell do you have? You didn't fill out the System Specs.

However, there are some Dell model SoundBlaster Xfi cards that are not supported by Creative or Dell for Win 7. On these models the Vista drivers do not work, Windows 7 specific drivers are required.
