Razer Imperator Mouse - Can't open configurator

I bought a used but in good condition Razer Imperator (original) on ebay. I received it and it worked right away - everything looks good and functions well with the mouse itself. It is very sensitive, so I went and downloaded the latest driver from Razer's website so I could adjust the settings and create a profile.

So, I downloaded the driver, installed it, and restarted the computer. The mouse still worked fine (lit up as well), however when I went into the Configurator, it starts to load and then I get a Windows message - "Razer Imperator Configuration Tool has stopped working". Tried restarting again, to to avail.

Then, I noticed that with the mouse unplugged, the Configurator opens - but then of course tells me that no Razer mouse can be found. So, I tried plugging the Razer in again - back to the Configuration Tool error.

So, I went back to Razer and downloaded the firmware updater, followed their instructions, and updated the firmware on the mouse. Restarted the computer, tried the Configurator again and nothing.

Then I tried uninstalling the driver/configurator completely and started over. Nothing.

I've also tried several different USB ports on my mother board.

I am using Windows 7 64-bit, with an ASUS 1155 motherboard.

Not sure what else to try.

Thanks
