I'll throw in a few suggestions for what it's worth.
I'd like to offer two fundamental things first. I'm sure you're sick of hearing everyone talk about how important it is that your mast is perfectly vertical, but I can tell you I wasted hours of time myself before I took this seriously. Second, are you sure you have a clear line of sight? This is actually the perfect time of year to take advantage of the sun's angle... the website below will help you. Just punch in your lat/lon and the position of the satellite (97 W for Galaxy 25) and it'll tell you when the sun is at the same position as the satellite. Go outside and make sure there's nothing casting a shadow on your dish. If you have trees nearby, you'll probably have to use your judgment if the leaves aren't on them right now.
With those out of the way, a couple more suggestions. Make sure you have the frequency, polarity, AND symbol rate set correctly in the Antenna Setup or TP Scan screen, or you won't see anything on the signal meter. Make sure you're set up for a universal LNBF also.
If you come up empty on all of these, I'd suggest if at all possible taking the motor out of the equation for now. Just put the dish right up on the pole, use only a single piece of coax (or two if you have the SF-95 in line) and see if you have any more luck.
Regarding your comment about being several degrees off: the place where the dish ends up may be several degrees off from what the angle calculator tells you as you read it off the dish mount, but you can't be several degrees off from the proper angle and still have it work... two different things
Hope this helps...
