Seems since yesterday I can´t call out. Neither punching numbers or clicking on call button does anything.

Not sure if that answers the problem, on Skype help I read this may have to with the latest update, which happened also yesterday or the day before.

If that is so, how can I de-instal an update, go back to the old version?

If not, anyone else had the problem and a solution?

one member suggested right clicking the contact, unfortunately it does not help.

You can get old versions here.

100.114 is installed, would you go back to 90.115 or 90.123 ? and if I download and instal either one does it automatically reset to the old version, thus overwriting the 100.114?

The image you show in the OP is a Skype Out contact. It is greyed out possibly showing that you may not have Skype credit.

The latest version moved all my Skype Out contacts to the Skype contacts list. I created a new contacts list which only shows my Skype to Skype contacts.

When you install an old version of Skype it replaces (overwrites) the new version.

Tks BB1950, credit should not be it, see pic. + Skyp has this automatic re-charge order from me.

Will try to over write the latest version and report back

Is your status by any chance set to Offline ??

Gosh, I am such a fool, it was meant to be on invisible. If you see someone walking around in Chiang Mai wearing sackcloth and ashes, that´s me!!

I was not trying to take the piss, but sometimes mistakes can simply be overlooked.

I didn´t think for one second you were trying anything like it, you were spot on, the simplest things are often discounted as being possible at all.
