My license does not work, or its expiry date is not correct.

If you go to the License page and you see that the license's expiry date is incorrect, you should check the state it appears in. If it is not in state: ACTIVE as licenses usually are, but it appears as: ACTIVE_P this means that the license is Active pending verification. It is also possible that WombatDialer displays the license in state: W/P that basically means it is not able to activate a new license.

Both these errors means that WombatDialer cannot talk to the licensing server to activate the license. In this case, if the license was activated at least once, it can be still be used but only for a limited period until it is properly verified, and thence it shows has an incorrect expiry date. WombatDialer tries verifying it up to that point in time, but if that's not possible, the license is shut down.

The solution is to make sure that WombatDialer can connect to the internet for license verification - it will use an HTTPS connection to our servers. WombatDialer requires outbound internet connetivity and cannot run without. It can use a direct connection or can go through a proxy (eg SOCKS) - to set ut up, look at Using an outbound proxy on the User Manual.

The User Manual also details all different states a license may be in - have a look at the The License page section.
