I tried to recycle the app pool after replacing the licence file but no result.

I don´t get this. If this happend to several of us. there is only 2 reasons as I can see:

1. there is some kind of date that have expired.

2. editor is comunicating with some kind of service at cutesoft. and that service has failed.

What do you think?

the old version of the editor seems to work fine.
