When I try to do a blindscan with my Coolsat 4000, nothing happens. The TP numbers seem to shudder at 00.000 and don't move and the percentage dial in the upper right corner stays at 0%. It did this one other time and I bit the bullet and reset my database. I really don't want to have to do that again... Has anyone else ever experienced this? and if so, what did you do? Thanks.
