That's what happened to me yesterday.
I was about to call someone when my Skype was terminated. The message said clearly that I had to download a new version because I was using an old one which they don't support anymore.
OK, I trashed all traces of the old version and downloaded the new.
Upon trying to sign in it stopped up again with the notion:
We have signed you out because you are using
an outdated version of skype.
I thought first that I made a mistake and deleted the new download again. Restarted the computer and downloaded the new version
a second time.
I found out that many other people have the same problem.
The thing is that my MAC is too old,
it is not compatible with the new Skype versions.
A support helper told me to go and get
an update for my MAC.
There are no updates for a 10.5.8 any more.
The end of it is:
If I want Skype I need to buy a new computer.
That's a way of making more profit.
"I am very sorry for the inconvenience this causes for you."
Sorry my foot!
I quote the Queen on that:
I AM NOT PLEASED!
NOT AT ALL!
