Offline installation?

hi, i was one of the lucky ones last night to be able to buy, download and install the mini queen. this plane is so awesome i don't know what else to call her (maybe princess would fit her better). persistence paid off for once. i always try to install software with my antivurs turned off. for that reason i also go offline. no problem with the airplane installation but the directx install aborted because the installer could not go online. no retry offered and then the installation was done (or so it seemed). there was no message saying that the NGX is installed successfully or anything like that. after that i did go online again and tried to download and install the latest directx. it told me that mine is a newer or equal version. so that should be ok. i have been able to activate the plane and all seems to work fine. is there anything to worry about? is the installation definately complete? any input appreciated. oh, and btw, I LOVE THIS AIRPLANE!
