The server 
ricardo.ecn.wfu.edu, which serves various gretl-related 
purposes (e.g. databases) has just been radically reconfigured: 
it's now a virtual machine run by our IT department rather than a 
box over which I have full control.
I'm afraid there may be some transitional problems.  I believe 
everything that you'd access via a browser should be OK, but 
access to databases and function packages via gretl itself may not 
be right.  I'm working on this.
For Windows users: the current snapshot
http://ricardo.ecn.wfu.edu/pub/gretl/gretl_install.exe
has some modifications that should fix any access issues.
