Grand theft auto v - how to veryfy game files ? error: err_gen_2_lib_2


when going into “online” mode. I get an error (translated from spanish), but it goes something like this:
err gen 2 lib 2.
data files are damaged, reboot system, verify game files or reinstall game"

In the instructions there’s " If you receive “Failed: zlib call” verify your game files." that seems similar.
How does one go about verify the game files.



I’ve just added in the configure–game options–arguments a -verify
started the game
waited for it to do the verifications. It doesn’t seem to redownload the game, so that’s good.
after the verif, the game starts and it works.
after you quit the game, remove the -verify from the arguments.

Hope this helps anyone else.
