I am trying to setup this router but it only allows 3 files and when generated I have 4, have tried a combination and can't get a connection.

Thanks

Then it seems to be outdated. That key is required if the server uses tls-auth, which is true for AirVPN's servers.

tls-auth

The tls-auth directive adds an additional HMAC signature to all SSL/TLS handshake packets for integrity verification. Any UDP packet not bearing the correct HMAC signature can be dropped without further processing. The tls-auth HMAC signature provides an additional level of security above and beyond that provided by SSL/TLS. It can protect against:

• DoS attacks or port flooding on the OpenVPN UDP port.
• Port scanning to determine which server UDP ports are in a listening state.
• Buffer overflow vulnerabilities in the SSL/TLS implementation.
• SSL/TLS handshake initiations from unauthorized machines (while such handshakes would ultimately fail to authenticate, tls-auth can cut them off at a much earlier point).

No combination will work because all four are needed. Sorry.

Have a look at https://www.asuswrt-merlin.net/
Maybe your router is supported.
Anyways, its better to tell your hardware if you need support...
