looking to downgrade after effect file version

Hello my name is Alexander! I have the latest version after fx! I will be glad to cooperate!!!!!!!!!!!!!!!!!!!!

I can convert your Project file from version 14 to version 11. It will open in your old program and you can work with it. Sincerely, Vladimir. Those people who made a bet next to me, they did not even understand your problem and what you want from them))
