Can't setup the repository server...

I tried to install Servoy on OSX 1.3.5 with Sybase as defeault repository server, but after installation and starting Servoy I get the message:

Can’t setup the repository server specified in the application preferences–>Could not find repository server: repository_server

The message is clear but how to solve it? The preference panel with DBserver is just empty. Note: I installed Servoy before on OSX 1.2.x and it worked just fine. I have the idea that something is wrong with Sybase (not starting??).
