Media Encoder 15.4 not connecting to dynamic link, not opening and not rendering.

I don't even know with what to start. On Friday everything worked correctly and since Monday I'm not able to work at all.
First Media Encoder didn't want to open at all. I thought that it might be down to Windows 10 update so I installed the newest version  of AE and ME(15.4.1). The program or didn't want to launch at all or didn't import the files. I go back to previous version and managed to render 4 videos before it crash again. After reinstalling it 3 times today, cleaning all the catche, removing folder 12.0 form C:/.../Adobe/Media Encoder I still have not working program. It isn't even connecting with project, it just frezzes.

My machine specs:
Win 10 64bit, 32 GB Ram
Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz 3.80 GHz
AMD Radeon HD 7900
All drivers up to date
