.cap are not compatible with C2 (which only opens .capx and .caproj).
The tutorials for C2 are in the ... section of the site.
You can also check the links in my signature for more informations and stuff about/for C2.
Please tell my where I can down load CC to research about techniques of some very interesting like Fighter...3D tank...etc.
I wanna apply them in C2 but have no clue..
