My computer sometimes plays 'Sonic Riders' with no problems. My problem is that it may take 10, 20 or 30+ attempts. It loads fine until I've chosen track, character etc, then hangs at the 'loading now' logo, although this logo remains animated. My computer is up to spec, graphics card drivers updated, I've run through the Windows troubleshooter, tried re-installing with anti-virus/firewall software turned off. Has anyone got any ideas? Thanks.
