Hello everybody,
I found the solution, but still I am searching to solve it, enshallah it will come soon ;)
When you install what guys gave to us, it won't work, normaly because it is from Flight1 security Files, that means, what we have it is for another Hard Disque ID, and you have to get your own install for your HDD, so, what we will have to do only, is to search for Flight1 FS2CREW PMDG 737 orginal one from the website :
https://www.flight1.com/ then search for a Dewrapper to get the file from the server according to your HDD, the current Dewrapper that we have it does not let us to call the server, it was only for the old versions :s, keep searching about this solution how to make work Dewrapper for Flight1 to get your files.
Cordially
