When I use my shortcuts to Steam/Condition Zero/1.6, they won't open. It just acts like its loading for a second, then it returns to doing nothing. I go to my steam folder and double click the steam.exe.. and that won't open either.

And I dunno if this helps.. but World of Warcraft can open and I can play that.. but UT2004 won't open either. It does the same thing as Steam.

Any ideas?

when you try to open it does it come up in your taskmanager anywhere?

cause some times my steam takes a couple of minutes to open and its annoying as hell

so maybe open it and wait a while =/

Did you recently create a new partition or format any partitions? Have you ever seen the windows file-checker thing when you booted up?

ctl alt delete, go to processes. Does the hl.exe process ever register as a running process when you open CZ?

I had this problem too, It started when I reinstall the game after a video driver update. It get fixed when I deleted the shortcuts from desktop and created again from main window game.
