Notepad++ 5.3.1 ftp cache issue

I have recently upgraded to the latest version of Notepad++ (5.3.1) and am no longer able to work with ftp files. I use the ftp plugin included with the program. When I go to open a file, the file cannot be written to the device and does not open. When I change the cache location for the account, the file will download and open, but when I save it, it will not upload to the server. Is this a known problem? I have reinstalled N++ multiple times and still have the problem. This problem is present on multiple computers that I have tried it on as well. Any ideas?
