Just a couple corrections: The concept of the game is old, this build (Continuum) has only been around since 2001, and it was written from scratch, with no code ripped/shared/etc. from the original SubSpace client. Continuum39pr1 fixed the prox bug: http://www.subspacedownloads.com/history/continuum.txt In every scenario, this problem has been attributed to the local computer, not the game. Although users may claim that the game is at fault, things like customized/broken/hacked operating systems, ant-spyware/antivirus, or other local software has been the cause. Properly installed and updated drivers and operating systems will always run the game, which is why a re-install is considered the 'last resort'. But it will fix your problem, barring the above mentioned items (this includes hacked/unserialized versions of XP).
