I have payed for a year since 29 december 2015 and i can't open the app's they say that I can only download the trail version. But my trail version for indesign is already expired so I can't use that.
I've got a mail that said the payment has been done.
If you have a paid subscription all you need is to download the program from the desktop application. If it reports itself as a trial, then sign out using the desktop app and immediately sign in again and the trial should convert to the non trial version. I assume you meant 29th November, 2015, but if you did mean 29th Dec then your computer clock is set wrong and that will probably really confuse everything.
