Hope I'm not in trouble :-(

Hey guys...new here. I have my first arline up and running and everythings going well...sorta.(Aeroline..get your tickets :-)) I wanted to add winglets since now they're allowed to one of my planes...I'm playing the sandbox game...first timer so it seemed appropriate. I pressed the button( to purchase winglets,spelling??), the screen loaded and then kinda got stuck ( nothing happened). Usually it says success or something then refreshes on it's own. this time it didn't. So i refreshed and all of a sudden a message pops up that says "Hacking is not allowed. Your IP has been logged" So..just wanted to say that I do not hack and how can I avoid this in the future. I'm pretty new with he controls so there has been a bit of refreshing...but this was the first time I saw that message. Some buttons open new screens IE the "open new route", and others kill the page I have up like" buy Used Aircraft" which sucks...cause then I have to remember what location I was messing with in the first place :-) Any tips?
