Any one know maybe why launcher (i downloaded new from server) is deleting game after i run it?

I downloaded new launcher and installed it. I downloaded game through it and patched. then i closed launcher. when i run launcher again all game that have been downloaded is deleted in more less 2 seconds. any1 know reason or how to avoid it. (for now i made copy of ESO folder).

I have this, too. Very annoying, because it takes hours and hours each time...
