I've had that happen myself Meethos.
I have now found out which lines are causing the problem so now people who are having the problems can edit the Buidl12 file themselves without causing any major problems with the game and without putting in an obsolete file.
Go into the PROGRAMCONTROLS folder and open up init_pc.c in Notepad or similar editing tool.
Find the following lines
<!--quoteo--><div class='quotetop'>QUOTE</div><div class='quotemain'><!--quotec-->CI_CreateAndSetControls( "General", "DCH_Quicksave", CI_GetKeyCode("VK_F5"), 0, false );
CI_CreateAndSetControls( "General", "DCH_Quickload", CI_GetKeyCode("VK_F9"), 0, false );<!--QuoteEnd--></div><!--QuoteEEnd-->
And comment them out so they appear like this
<!--quoteo--><div class='quotetop'>QUOTE</div><div class='quotemain'><!--quotec-->// CI_CreateAndSetControls( "General", "DCH_Quicksave", CI_GetKeyCode("VK_F5"), 0, false );
// CI_CreateAndSetControls( "General", "DCH_Quickload", CI_GetKeyCode("VK_F9"), 0, false );<!--QuoteEnd--></div><!--QuoteEEnd-->
Save the file and start the game, hopefully this will now work OK.
These two lines are for the Quickload/Quicksave mod.
I don't know if it really is these two lines that are causing the problem so some other code that is not run when these lines are commented out could be causing the problem.
I'll leave working that out to someone who is more of a codemonkey then I am, all that I know is that it works for me <img src="http://www.piratesahoy.com/forum/style_emoticons/<#EMO_DIR#>/icon_wink.gif" style="vertical-align:middle" emoid="

Commenting these lines out will just mean that you can't use dchaley's Quickload or Quicksave, which is unfortunate.
I believe that everything else will work perfectly OK.
Now if you'll excuse me I've got about an hour left and I think that I want to use it to play the game <img src="http://www.piratesahoy.com/forum/style_emoticons/<#EMO_DIR#>/smile.gif" style="vertical-align:middle" emoid="
