Cute FTP 7 Home

Jeg har aldrig haft problemer med upload før, har altid benyttet Global Scape/Cute, men pludselig vil det ikke lykkes mere. Jeg får hver gang følgende fejl meddelelse:

The server forcibly closed the connection.
This normally results from a loss of the connection due to a timeout or a server reboot.
1) Try connecting to the server again later.
2) Verify that the problem is not local by trying to connect to an alternate server.

Hvad er det som går galt? Jeg har skrevet til webhotel udbyderen, og der siger de at de ikke har nogen problemer med login.
