I'm trying to install PVelite 2014 using some links I got through this forum, however I can't seem to get pass installing the licensing key. I keep getting an error "Invalid Key- Not within installation period".

I've tried setting by date back and I still get the same error.

I've installed it before on a different pc using the same method however now I keep getting the above error on this pc and another one.

Is there any way to remedy this?
