Hi Kalle,
I am not sure "webdrive" is that common of a software at least in this forum. There have been reported problems with various backup softwares not working with the 320 though, which makes me wonder if the problem you are having might have something to do with your "webdrive". If that is possible, you could try to see if there are any options or settings to adjust in "webdrive", of if this route fails, experiment a bit and try using another ftp option of which there are several. I would try just using IE or FireFTP if you are using Firefox. If your client then works, you will then have a workable tool which is not difficult to use for your tasks. Good luck
