Hi everyone, I wonder if someone could help me. I'm trying to run the game in my computer. Although it is x64, my Ubuntu version is 12.04 LTS x86. I'm getting the following output: ======== Cache: 200 (total: 7926) MiBTIMER| InitVfs: 105.935 msSound: AlcInit success, using PulseAudio DefaultTIMER| CONFIG_Init: 4.61546 msTIMER| InitScripting: 2.69009 msX Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 153 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 13 Current serial number in output stream: 13UserReport.cpp(515): Assertion failed: "!m_Worker"Assertion failed: "!m_Worker"Location: UserReport.cpp:515 (~CUserReporter) Call stack: (0x8481150) /usr/games/pyrogenesis() [0x8481150](0x8442734) /usr/games/pyrogenesis() [0x8442734](0x8443534) /usr/games/pyrogenesis() [0x8443534](0x844383a) /usr/games/pyrogenesis() [0x844383a](0x81ee0c6) /usr/games/pyrogenesis() [0x81ee0c6](0xb6bd7f51) /lib/i386-linux-gnu/libc.so.6(+0x32f51) [0xb6bd7f51](0xb6bd7fdd) /lib/i386-linux-gnu/libc.so.6(+0x32fdd) [0xb6bd7fdd](0xb74768ec) /usr/lib/i386-linux-gnu/libX11.so.6(+0x398ec) [0xb74768ec](0xb7358687) /usr/lib/i386-linux-gnu/libSDL-1.2.so.0(+0x42687) [0xb7358687](0xb7476a2b) /usr/lib/i386-linux-gnu/libX11.so.6(_XError+0x12b) [0xb7476a2b](0xb747382d) /usr/lib/i386-linux-gnu/libX11.so.6(+0x3682d) [0xb747382d](0xb7474827) /usr/lib/i386-linux-gnu/libX11.so.6(_XReply+0x2a7) [0xb7474827](0xb77050cf) /usr/lib/fglrx/libGL.so.1(+0x790cf) [0xb77050cf] errno = 0 (No error reported here)OS error = ?
