Troubleshooting
While ITP is designed to be as easy to use as possible, the setup of current
generation wireless transmitters can sometimes be complex. As such, there

scenarios that you may run into. This chapter is intended to be a reference
for situations in which you are experiencing problems - if you are up and
running you can safely skip the remainder of this section.

before moving ahead. The main issue (especially for those using Windows XP
Service Pack 2) is the presence of a software firewall on the computer hosting
ITP. Most firewalls block all incoming traffic that was not requested by the
host machine - unfortunately, the FTP connection the camera is attempting
to make with your computer is such a connection and will often be blocked.
If this is the case, you must make an exception to the firewall to allow ITP to
accept incoming connections - if the firewall allows you to do this on a per-
program basis, add an exclusion for itp.exe (by default this will be located
