Yeah I head the samething. the opengl error but!! I update my nvidia card and now it does work. Only afer 5 min the game crashes. And dont try to patch anything, like Jk 1.01 or ja+ cause then you get the V_UI created failed error. Wich means you need to reinstall. And that doesnt work cause you crash after 5 min again

Conclusion

Microsoft or Lucasarts need to make a vista patch and pronto.

If you have a solution please email me
