Hello, first of all i have to say that i am very disappointed.
You host your website on server which has installed GNU/Linux system which is a product of open source community work. You use Apache Web Server which was created by GNU/Linux community, same as PHP. You even use Ubuntu Font for logo of ArtRage and you still doesnt support GNU/Linux - this is called rudness.
You use amount products of our work and you still cant provide support for platform where all this software was created. You should be ashamed. I understand that this is business but all companies has something which is called "moral backbone" and you have this thing on very low level.
I read about WINE - dont even embarras yourself and propose me this buggy thing. Why i have to have much lower experience with your software than Mac or Windows users? We gave you all our software for free and you cant provide us your product for money which we want to pay you. I cant find word for this ridiculous situation.
