Win 7 64bit Ultimate

Geforce 9500

Downloaded latest version (today - full download not a patch over) after getting lock-ups yesterday, and I am still getting them.

I don't alt+tab etc, just run round as normal doing in-game stuffs, then the game locks / freezes although I can still move the mouse. I waited for it to 'unfreeze' last time for about 5 mins, no luck , had to alt+tab and kill it in Task Manager.

No crash logs, no error messagem -- nothing I can show to say 'here is the problem' .... /bangs head

The only thing showing in the log files are repeated 'failed to load' various .dds files.
