Have you checked your Latitude, and especially your Longitude, settings are correct?
Remember negative Longitude readings = West, positive = East, as you have set your dish up on 5W I assume this is the closest satellite to your Logitudal position.

You seem to have only just installed Blackhole 3.0.3 try downloading, and installing it, again:

The latest version is 3.0.3H but you can quickly update this via the Blackhole menu options.

When you have installed it, and set up your Tuners, if Tuner A is the cable connected to your motor then set this up as Config Mode - Simple, Mode - Positioner, and enter your correct Latitude, & Longitude.
Tuner B as second cable from motorized dish.
Once completed try using the manual scan option, select a satellite and enter suitable transponder details, which can be found on lyngsat.com.

If this fails to find a satellite you might try using Diseqc 1.2, and then use the setup options, to move your dish until you get a signal.

Please post back if you have any problems, and take it one step at a time.
Good luck.
