I am having the same issue. I set it to "skip planet update" and only download USA-East and West since that is all I need. Yet it sits there, not doing anything, stuck at "overall progress 12%". Output window is blank. I do not want the entire 45-200GB planet files on my system since I do not have much space on the primary 128GB SSD and still only 60GB free on my 500GB backup drive. I have the program set in the processing parameters to use the related folders on the 500GB D: drive.
When the program first starts up, I do see this in the Output, but once it finished "creating contours for usa_east", the output windows clears:
Preparing region usa_east directory.
Preparing region usa_west directory.
Found 2 regions to process.
Planet file download started.
usa_east contours update started.
Resuming broken download of planet-150906
Bad response code from server 404 - Not Found.
So how do I get it to progress without forcing the download of the entire planet files? All of the settings and servers are default servers that come with 1.2.271.

For download method, I have to use HTTP since torrents are blocked by my connection.
