Can't deploy

Hi,

every time I try to deploy anything (SDA file, EAR file,...), I get the next error:

Error received from server: CmdXmlFactory could not find Top Element within String: "null".

The strange thing about that is that I could dploy without problem some weeks ago, and suddenly this error came.

I get this error when deploying with the SAP deployment manager, and also when deploying with the Sap netweaver developer studio.

Thanks in advance.

Gregori Coll Ingles.
