What can I do against it, I really need to update my site soon!
All help is very appreciated, many thanks!

Isn't there anybody who can help me?

For the 1st error message increase the server timeout to at last 120 seconds. (control+o, connection, server timeout)
BTW the message says that you only can be logged 1 time, and failed logins (for example with timeout) are counted. If you get the message you must wait up to 5 minutes for droping died connexion.
The 2nd error message is because server failures, i have tryed with smartftp, ftp.exe and cute ftp pro.

Thanks!!!
