mouse rate

I have my mx518 and I wanna change mouse rate but I can't :<. I downloaded USB Mouserate Switcher "usbmrs11" for windows vista and this piece of shit says then I have an unknown system version ;<.
I have windows vista familliale premium ( lol? ) HELP
I dont think that there is mouserate changer for vista..
try to serch in google.

Works for me
This program doesn't found my mouse. :< It found just something like this Peripherique d'interface utilisateur USB :p
It just says USB HID at my place , but it works ;)

1. Restart Vista and repeatedly press F8 to bring up the boot menu. Select 'Safe Mode'.
2. Run the following command from the Run box: bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS
3. Run the following command from the Run box: takeown /f "C:\Windows\System32\Drivers\usbport.sys"
4. Run the following command from the Run box: cacls "C:\Windows\System32\Drivers\usbport.sys" /G username:F
(replace username with your username)
5. Open C:\Windows\System32\Drivers and locate the existing usbport.sys
6. Rename usbport.sys to usbport.old
7. Copy the usbport.sys in the file below (which corresponds with your vista version and desired usb frequency).
8. Restart Windows
9. Run mouserate.exe to verify that you now have a 500/1000hz polling rate.
thank you guys, it works ;>
