Problem with game.

To the opening poster, maybe you could start by forcing safe mode.

By the way, what operating system are you running there?

Anyway go into the options on your launcher and start with the force safe mode. If you can get in then you can try by gradually adjusting the settings upwards from shader 2.0 etc. (untick safe mode at that time)
If you have 'update all resources at once' ticked, untick that. Untick weapon beams and wepon trails in the advanced dialog box.
Of course double check and make sure that your video card drivers are up to date and if you run windows, that direct X is also up to date.
Good luck and post screen shots and any other messages you get from the game. The more info presented the better the community will be able to help.
