If you are getting that trial option to install it, kindly go ahead and install the software. We can certainly activate it after installing it.
We would like to know the results after you followed second link.
Did you try all the steps mentioned in second link? How does the hosts file look like when you opened it?
We would also like to inform you that the trial version has no functional difference when compared to activated version.
Kindly provide the screenshot of trial screen of the software and the hosts file, so that we can have a clear idea about the machine.
Thanks,
Atul Saini
