Yeah mate. Tried uninstalling and downloading it again. Still get the driver error.
The thing is, even without Kies installed I should still be able to use it as mass storage. However, whenever I plug in the phone I get the error. The phone is on the MTP Application page. It says "Connected Press the home key to quit Samsung Kies". This is on the phone even if Kies is not installed. Also the phone does not appear as a mass storage either here or when I press home.
I'm getting the same problem on both my laptops. One is running Windows 7 64 bit and the other is running Vista 32.
I'm baffled and google isn't helping.
