...put my new airplanes and it only loads until 60%

Well, I gotta tell you, ENG Sound Mod, and A/C installer, are way, way outdated.
Latest A/C installer (buttons) is v3.8, and if you add certain new planes that require newer buttons, then you are going to get a 60% crash.

Most have moved on to Official 4.09m patch, and latest Mod Packs, either UltraPack 2.0 or HSFX 4.11.

If you want to get your ENG Sound Mod working with new planes, you could try getting latest buttons from SAS website:

but I suggest you upgrade to 4.09m and one of the newer Packs instead, or 4.09m and the latest SAS Mod Activator.
