GWX 3.0 working well but WAC 3.0 problems still...

[robbythesub]

I have installed GWX 3.0 and it is great as expected thanks guys, however I would ask again whether anyone has had problems with ctd and problems runnig WAC 3.0?
Hansolo has been very helpful to me, but despite several re installs, I still cant get this version of the game to run right, so wondered if anyone else can offer advice if they have heard of this problem and resolved it?
I have it installed on the same drive as GWX but have it installed separately to a different named folder with Multii SH3 to create the different game save folders.
My system is high end and I have windows Vista 32 bit.
The problem I have is that it installs, loads the first screens, including the movies to the career screen.
At this stage I can play any of the academy missions fine with smooth play and no problems.
The problem occurs when I load a career, go to the crew and sub screen, make some adustments to the crew numbers and equipment etc on the sub and start the career.
It loads to about 90% through and then I get a ctd.
At other times if I make no adjustments to the sub or crew, it will start with the sub in the pen, but I get a very loud hissing sound and strange colours to the graphics.
Finally, I got it into a mission and it played beautifully for a while until I tried to manually move an officer from rest to the bridge, at which point it sometimes crashes too.
Hope this gives enough info for someone to help me?
Many thanks in advance guys.
