Issue with text on ''screen guis''

[wintaxe]

Hi, so, I've downloaded MTA after a long time of not playing to play on one server when I've encountered this problem with my game or computer possibly, I've reinstalled GTA and MTA nothing helped, here's the issue

The text I type in login screens or ''prompt boxes'' is for some reason invisible for me

And also in a few other ''screen gui's'' text refuses to show, for example I'm at character selection in a server and nothing shows, yet I click and it seems something is there (No it's not a problem/issue/complaint about a server, same thing happens in a different server just in a different way) 

The so called ''invisible text'' I type in a prompt box https://prnt.sc/DF2KGA9mOa1K

As I've said, it's probably a problem with my MTA game since the same happens in a different server when I type anything into the login screen prompts

Has this happened before? No, I've played MTA long time ago on the same computer and there weren't any similar issues to this

Hi, welcome to the forums.

There are a couple of problems that I've seen from your MTADiag link, most notable the fact that there are some non-standard GTA files in your installation.
Please perform a clean install of your GTA:SA game. Make sure you use a legitimate copy of it. You can find ways of obtaining one here: https://wiki.multitheftauto.com/wiki/Where_to_buy_GTASA

Your MTA installation has not been properly done. There are files missing and errors/exceptions being thrown.
After reinstalling your game with a legitimate version, make sure to perform a clean install of your MTA as well.

Last resort would be performing  a clean reinstall of your operating system.

I have reinstalled MTA multiple times, how would it be missing files is what I don't understand
