Well, first of all, if I should add you in Skype, I need youre Skype name (simply pm me, I didnt found this information in your profile).
Second point, I test the beta of Lackeyccg on a xp pro an an 64bit win7 PC at home, and it starts well (at the moment, I havent realy play a round of magic on it, so I only can say, it will start, but I think it also will run well).
The pont is, the reason, why it wont start on the pc of my parents, must have something to do with the PC of my parents. But what? Ok, it is a home edition, but what else?

I dont now when I next visit my parents.
By the way, your Lackeyccg is a nice peace of software. I realy like it. Thanks for the hard work with it.
