I purchase software and protect my swf files it is great software.

Hi
i am flash designer.
i have use it, it can defeat all new version from decompilers and run on all flash players (5,6,7,8,9) i test on all decompilers and players, thanks developer

I was frauded by this thing, it increased my file size, made it unplayable in older versions of the Flash player and few days later I found that a customer of mine was reusing my so protected code, when i asked him he said that he used flasm to remove some trash he found and then was able to decompile the movie and get back my exact actionscript:(

The use of silly tools like this and like SWF Encrypt that inject trash code might make the new versions of the Flash player unable to play your files, the idea of these tools that they simply mess up some of the unused tags to confuse the decompilers, a cheap and very easy to solve trick...

SWF Protect doesn't niether obfuscate nor encrypt swf files, all it does is adding juck code to the file that crashes decompilers.
This lousy trick (which is also used by SWF Encrypt) can be solved easily, and very soon all decompilers will have an update to drop the junk code and expose all your valuable actionScript.
If you are looking for a better protection, try secureSWF Lite it's a free, real, functional and supported Flash obfuscator.
