Recently active topics in Wuala tagged with sign in

Hello,
when I came back home today, I found that wuala installed update 87 and 88. I got the message that wuala would restart automatically as soon as it was idle but I wanted to help a bit an restartet the programme manually. Since then I'm not able to sign in. I always get the error "Sign in failed; Reason: element never existed, [2,54307,1]. I am really sure that I use the correct user name and password.
Thanks for help.

The first time, I receive the following error (I've obviously got net connectivity though):

Sign in failed.
Reason: com.wuala.common.exception.CouldNotConnectException: Meta Server Socket could not connect to /85.10.210.141, port=50030, type: META, Connection refused, [2,46557,1]

(tried to telnet to that address & port and the connection was also refused, so not java's fault)

Subsequent sign in requests read:

You have never signed in on this computer before.
Please connect to the Wuala network in order to sign in.

I want to use Wuala with my laptop. I have already used it on my stationary. They're both running XP. After installing it on my laptop I'm given the following eror message when signing in: You have never signed from this computer before. Please connect to the wuala network in order to sign in.
