Hi. Here's the problem: I have followed the instructions for installing the P2 drivers onto my computer (Windows 7, 64 bit system) and found that the drivers for the device and card reader are where they should be, as advised. However, as soon as the HPX is disconnected, the drivers disappear! I have tried many times, but still no luck. As you can imagine, this is driving me round the bend, so I'd be very grateful for any advice. By the way, I can transfer the data all right, but the footage after conversion in Cineform (using Sony Vegas to edit) plays at what looks like double speed. Cineform have told me that the P2 drivers must be installed, then everything will work as it should.
