Web edition 13.1 license..

Quartus web edition does not require any license file. I think we can simply ignore the message. I've got the same problem before and after the date, the message simply gone away.

I believe the web edition generally would have 30 days trial period. After that, you might need to use the subscribe version to allow complete functionality of the Quartus II.

Nope, web edition does not need any 30days period. Only subscription used the 30days fyi

Nope, web ediiton does not require 30days. It should be free, only sub use 30days

There got "do not display this message again". just select this option on notification message and it will go away.

As per my understanding, you may try to contact your Altera Local sales representative if you need a 60 days evaluation license...
