Dependency file not found + Failed to save target content

Hi!

I feel that I have multiple problems with my SDL Trados Studio 2015.

1) It started with "Dependency file not found". I followed some advice, and although I could not do it like I was told to, massage disappeared. But I see that I get error massage for each translation unit, it is about source language, you can see in the window.

2) Now I realized that I can not save target content. "Cannot find central directory".

How can I solve this? My deadline i already here.

Thank you in advance!
