Adobe Illustrator text disapear

Hello everyone!
I have a big problem with Illustrator. Some texts no longer appear (whereas my colleagues can see the texts very well when they open the files at home) and the outline (blue selection outline) of other texts disappears completely when I want to move them (+ no vision of the text moving, it remains visible in the same place, then appears where I finally release my mouse click).

Please tell me someone has the solution :'(

p.s: I've already uninstalled Illustrator and reinstalled, but it doesn't work.
