I'd like to point everyone in the direction of our Grand Theft Auto: San Andreas forums at GTAForums.com. There is a specific forum for Xbox and PC information and a PC troubleshooting forum has just been opened. There are also forums for gameplay help, general discussion and cheats and tricks where the first San Andreas PC cheats came from and are constantly being found. With over 700 users online at the time of writing, you can be assured that your question will be answered.
On a similar note, Take2 Games has opened a tech support section for San Andreas PC. Their FAQ only holds one question at this point. Thanks to our partnersite PlanetGrandTheftAuto for the heads-up on this one.
