I have installed Guitar rig 7

Hi, I'm new here. I' m wondering if I will allowed to use Guitar rig 7 limitless.
I have to say that the sounds of guitar rig's amps are amazing. I play on a Strat just since recently. I have been playing on an acoustic guitar for several decades. The electrical guitar is a little new for me. I d like to avoid buying an amp, I play alone with a headset.
I saw that there's a special price now for Guitar pro 7 until the 31, but I would prefer to continue with a free version, if possible. Thanks.
