Is the file stuck in the transfer queue window (at the bottom)? If yes double click it to get the log. Then post the log here.
Well, it did appear in the tranfer queue when I tried it yesterday. And it appeared in the Web window with a size of 0KB. Today it doesn't even do that.
However, here is an extract from the log:
