American Express download stopped working...

"Client application or version is not supported by this server."

I've been using gnucash for about a year, and all has worked fairly
well. However this past week my American Express credit card download
stopped working. I've collected a log with AQOFX_LOG_COMM = 1, and
attached it, with userid and password changed, along with all large
numbers, however I've kept the smaller ones. 

I also tried appver 1800, same result

Is anyone else seeing this problem? Is there a known solution?
