I Have forwarded this to our web master to have them correct the problem, should be fixed some time today.
The license for Power gallery, and Power Store also allows you to set it up on 1 testing Domain, and 1 live Domain.
You could use the 1 testing domain to set up your own Demo and remove the WebAssist branding.
In the next upgrades, we are planning to use MySQLi, but I do not have a time frame for when that will happen.
