Just called them, money received. But now they want the fees also. I'm refusing. If they had sent the bill to the right address to begin with, this wouldn't have happened.
In other news, making a new linux x86/qt4.4 compile of the tanker demo. Build environment setup, should have a binary able to run on the target platform within a few minutes. I'm having a blast with QT to be honest, as I started coding in it a while ago, and I'm really just starting to "get it". The fast prototyping ability of new graphical user interfaces is awesome, and the customizability with both stylesheets and inherited widgets.. I like it :-). I usually avoid changing widgets, it's a bit of a mess since I'm still rather new to the language, but I will do my best at it soon ;) .
