Flash security
I'm currently preparing a seminar for my college course "Internet safety", and I'm writing about Flash security in various scenarios. It is practical work, so there will be a lot of free code to look at.
When I'm done with it, I'll be putting it in some small e-book for everyone to read.
Stay tune. 
Trouble activating Flash?
Well, I reinstalled my Flash CS3, entered my serial number, but when it came to activating it, I couldn't. Probably because I'm in Croatia which isn't part of EU and definitely isn't in America.
Anyway, solution is tied to proxies. The thing that worked for me was to set up proxy settings in my default browser (Mozilla Firefox).
On this site I found proxies which I could connect to. So I went to Tools -> Options -> Advanced -> Network tab -> Settings. Choose Manual proxy configuration, enter proxy address and port, and check Use this proxy server for all protocols. Now you can close windows and test if your connection is working. Try opening your home page or any page you want. Connection will probably be slower, but it should work. If it doesn't work you either didn't input proxy settings correctly or server you wish to connect to is offline.
So now your connection over proxy works. Now open Flash and try doing activation (normal activation, not over proxy).
P.S. You can check if server is online with opening cmd, and ping it. If it responses, your connection should work.
Hope it helps someone, because I lost all day on figuring out activation, and I hope none else will suffer anymore.
