Registration Error


I have a little problem with the registration of Sambapos V5.
I bought Sambapos and installed it.

Later i got this error:

Can somebody help me with this problem?


Can’t read that language but looks like activation message.
Have you bought a licence for v5?

The language is german.
And we bought V5.

That is an older version. Update to latest version and then try to activate.

Where can i download latest release? The link in this forum is ofline.
