    Preciso de uma FIX que possibilite instalar os patches 5.0.3 e 5.0.5 no jogo Football Manager 2005, e rodá-lo no Windows 10 e 11. Até 2020, era possível instalar o jogo, os patches de correção (5.0.2, 5.0.3 e 5.0.5) e jogar o game normalmente em Windows. Porém, atualmente isso não é mais possível. Há uma FIX que permite rodar o jogo em Windows 10 e 11. Só que essa FIX só serve para o patch 5.0.2. Quando instalamos os 02 últimos patches de correção (5.0.3 e 5.0.5), o jogo não funciona mais.

The goal here is to prevent a user from accidentally sending trash data through the system, as well as protecting them from potential security issues. SANITIZE: Data that is input (either by a user or automatically) must be sanitized. This lessens the possibility of XSS vulnerabilities and MITM attacks where posted data is subverted. VALIDATE: All data should be validated as much as possible. Even when you sanitize, remember that you don’t want someone putting in ‘dog’ when the only valid values are numbers. ESCAPE: Data that is output must be escaped properly, so it can't hijack admin screens. There are many esc_*() functions you can use to...
