Xtreme Gamer is "not Supported by the Application" Problem. He

Question

My SoundBlaster XFi Xtreme Gamer has suddenly stopping being detected by my creative software, such as Volume Panel. The drivers are installed, and when I hover my mouse pointer over the volume panel is still shows "SB X-Fi Audo [E000]" which is the sound card, but when I doubled click to open the volume panel it says that "The current selected audio device is not supported by the application. Do you want to select another audio device now?". When I click "Yes", it doesn't show anything on list besides "Windows Default Audio". This happened out of no wheres, with no changes at all to my computer. Volume Panel was working yesterday, but when I woke up today it wasn't. I have no idea what could be causing this, or what caused it... I did update the drivers about a week ago, but it was all working fine since, until today.
I haven't installed or uninstalled anything since it was working properly.
I tried reinstalling drivers and software, and it did not fix anything. I also uninstalled everything including drivers from computer, and used my original installation CD to install everything over again. Every installed fine, but then for some reason it would not install the drivers. Windows was detecting the device, but when I went to install the hardware manually, it would ask for CD to find some files to install... it said this twice, I located the files it needed, and each time it would complete the process it would instantly reboot computer without notice. When the computer was booted up, it would ask then ask again for the Creative CD to install the detected hardware. So I for awhile I could not install the drivers, but for some reason out of no wheres it finally installed when I used the update installation file I downloaded from Creative.com, even though I had tried the same thing a few times, it for some reason installed drivers. But now it is all installed again, my software seems imcomplete and will still not work with the sound device. What seems to be the problem here? Only thing I can think of now is the installation for some reason became corrupted. Only way I can think of fixing it is reformatting my whole computer, but as of right now I don't feel like spending a whole day doing so.
Is there anything that you can think of to fix this problem? I have had the sound card for about a year now. As of right now, I am still using headphones in the soundcard, but it doesn't sound good at all as I can't change anything in software. I also noticed that is no longer has as much installed as it would if I used my original CD. It doesn't have an option to switch sound modes anymore. It also doesn't now have "X-Fi Soundblaster" in "Add/Remove Programs" list. All it has in Add/Remove is "Creative Audo Console".
I uninstalled everything I could and deleted left over files in the Creative directory, so I deleted the whole folder after.
Only other thing I can think of is something in the registery is messed up, and causing the sound card not to be recognized. I also have WinXP SP2.

I spent yet another hour or two trying to fix it, and nothing changed.
I put it into a different PCI slot, and made no difference.
PCI slot doesn't seem to be the problem, I am thinking it is something within the registry itself.
I also put in the CD and there was no option to remove drivers, so I just went ahead and tried overwriting them, but that actually made things worse. My computer kept rebooting over and over when it hit the Windows Boot Up logo, and had to go into safe mode and do a system restore to get it back to normal.
It also keeps asking for the CD when windows loads and it detects the soundcard.
It will ask to locate acouple files, I do what it it says, but just as it is finishing installing the drivers it reboots the system.... when windows is loaded again, it will ask the same thing over, and will keep giving same results.
There isn't anything to completely remove all the creative files and folders including the 00's of registry keys. Maybe Driver Sweeper or Driver Cleaner Pro might help? ill try them, but as of now im not bothering with the soundcard.... ill just reformat. I just hope it ain't the card itself, because I am a month over the one year warranty, and the azzholes from creative said there was nothing they can do about it.
That alone made me want to turn to a different brand next time with better support. Creative has some of the worst support I know of.
They tend to leave people hanging with their defecti've hardware. What I don't get is, that the card still installs the drivers at times, and it will still work but the software won't.
I have been using it this whole time, but seems to freeze up my Guildwars alot.
It still sounds good, way better than Onboard, just not as good as before because there were no options for change mode, or couldn't access the equalizer.
Anyone know of any programs that will completely remove everything for the Xtreme Gamer Creative Software? Including everything in registry.
Also, is it possible that there might be a Windows Service that might have an effect on the problem? I tried enabling a few things, then try rebootin and reinstalling, but didn't seem to help.
But then again, I am not sure which services would cause the problem.
Definately something happened with the last Creative Driver update, only took a week afterwards for something to go wrong.
