Remote Upload Freeze

I am currently wrestling with a file that refuses to upload to the server. I attempted to do a simple New Generation, and it stopped in the middle of the upload. I have had much success doing this in both b13 and b14 versions, but today the upload stopped midway just like some of my old Pan6 files. (I learned in Pan6 never to upload a file over the internet, but wait until hardwired into the server.) I am currently using the internet and my server is at a remote location. I usually can remove a misbehaving file from the server only from the server computer itself. I have not had any success so far in removing a misbehaving file remotely. Again, my definition of a misbehaving file is one that will not upload components remotely during a normal New Generation.
