"No description found" when saving a package

Hi everyone,

Primary platform is Framework 2.0 and Sql25k 64-bit

When I try to save my DTSX package from my client to the production server I get this error:

"No Description found"

Either Windows or Sql authentication.

Does anyone have ever faced this drawback?

Thanks in advance,

Any idea?

Is something related to Visio 2003? http://support.microsoft.com/kb/922546
