Hi, 
 from a desktop-pc I tried to use the portable version,in a public library.
All I got was an error message. I suspect there is a proxyserver, also I found
a form for this purpose in the copier. But I do not know the name of the
server and if, I do not know whether this is the solution-does someone else
have a hint? When using the netbook in this place, Wlan, it works!!
For your help-thanks a lot!!
Best regards, 
Duc

PS: Many, many thanks to the developers of this copier-it is a great help for
my eductional purposes, which I can do without internet-access
