Mathematica 10 - unable to connect wolfram cloud: OpenSuse 13.1

I did an downgrade from OpenSuse 13.2 to 13.1 (more stable version), and now I am not able to connect wolfram cloud.

It’s hard to say what might be the cause of this.

First, try resetting Mathematica’s preferences to their default configuration. See this article:

I can’t see the picture very well, but it looks like $CloudBase isn’t defined for some reason. What happens when you evaluate $CloudBase?

Hi,

I did a reinstallation , also the OS, and now it is ok.
