OK. I have the following error when starting the client:

"Object reference not set to an instance of an object."

I worked yesterday fine, i sync files and used it fine. I can log into the
web interface fine, just the windows client will not startup. I get the
icon in the systray, a green arrow, then a red one and then the error. it
then closes.

The server is the latest version of the open source version running on
Fedora4 in VMWare.
