As throughout several beta tests, I had various versions of the software installed on my machine, I had some problems getting the USB drivers to install correctly with this release. Should others encounter this problem, I've posted instructions as to how to resolve.

============================================
Possible Problem with the latest ProntoPro NG software.
============================================
I'm using XP Service Pack 2 and following update of the 2.1.4 software for the ProntoPro NG series, the USB driver for the remote could not be located. I've already sent an email to the ProntoTeam for this issue and am awaiting a reply.

For your convenience, I've posted the steps to manually reinstall the driver below.
