the first problem its from your cs , most cs are blocking commands gl_ cl_ r_ mtod and binds that server sends you. wonder why ? This are features that prevents servers from injecting players with Auto-Connect commands or preventing Game Menu modification . Some fake servers even can send you viruses or keyloggers , so command block from your cs client its a safety measurement. You dont want to open cs and be redirected to a server you dont want.
Second problem, i don't know about that maybe cards were disabled .
