How do I set up a route to a local network when using Private Internet Access VPN?

I am using Private Internet Access (PIA) on my Windows 7 virtual machine and am having trouble getting on to the local network or even pinging it for that matter.

When PIA is disabled, I can get access to the network so I know that it has something to do with the problem.

I have read that there are issues of this kind where there is a routing issue so I’d like to try to see if this is a solution.

My local network is of the bog standard 192.168.1.x variety so I tried this:

route add 192.168.1.0 mask 255.255.255.0 192.168.1.1

but this has no effect. Now, from what I understand, it should route everything to an address in 192.168.1.x to use the 192.168.1.1 gateway.
I cannot ping 192.168.1.1 so I guess this may have a significant bearing on this too??

Have I got the command wrong or am I pointing this to the wrong IP address?

Thanks
