Irender nxt trial period extension?

Hi everybody :)

For some time i am using Irender nxt demo and must confess it is an exceptional program really.

I am novice to 3d modeling/rendering and it is now my hobby only.

Pecuniary problems restrain me for now from purchasing the commercial version, though i wish very much.

I just wanted to ask you is there any possibility to extend the trial period working /any temporary code to enter?/ as my efforts to deinstall and reinstall the newly downloaded demo went crash, saying that the trial period was expired.

Any response of you would be highly appreciated :)

Have a nice day!
