Question: Maple and Geometry Expressions software

Hi, is anyone using the Geometry Expressions software together with Maple? I've found about this software on forum and installed a free demo version. It is using symbolic geometry, which I haven't been able to find this feature on other software, and can work very well with Maple, but unfortunatelly, my demo version doesn't work properly, and their oficial website http://saltire.com/ has lots of errors 404 page not found. I have requested support, but have had no answer so far. I was so happy finding this software, but now I am thinking maybe wasting my time. If you are using it, or maybe think it would be good to give it a go, please let me know if it is working for you. A particular feature which is not working for me is 'creating angles'. Thank you.
