Suse 13.1 / KDE Skype

Hello there ,

I'm kinda new here , but trying ...

Last night I updated my openSuse distribution from 12.3 to 13.1.4 .
So far so good , everything worked perfect except skype .
I checked and I found several posts about pulse audio , so I did as it says here https://en.opensuse.org/SDB:Skype , step by step .

But nothing yet . Despite I see the "Welcome" window for skype , it then dissapears . I don't know if it's just me or someone else ,and I also don't know how to fix it ... Any suggestions about what might be wrong ?

Thanks in advance !
