I have installed a new installation of Datasync.

I have installed Sles 11 SP1 64 Bit and Datasync Build 428 with the security patch.
If i want to start the web manager ( i'm getting the following error :

Page Not Found
The page or feature you have requested cannot be found or is unavailable at this time.

Please check the following items for troubleshooting:

Check the website URL for accuracy.
Does the URL require SSL?
Is the specified port number correct?

If your request continues to fail, contact your system administrator.

The color scheme looks like from datasync.

I have restarted the server but it didn't help. I have tried other browsers but also no go.

What could be the problem?
