Visual Studio 2013 linker confusion

Question

I get the following errors when compiling(running build in VS) my latest project. I have read other questions/answers here on this site, but so far no luck to fix my issues.

I know my problems are related to linking the different libraries, but why I get this problems I don't know.

The compiling has been working OK before, but no I can't get rid of the errors.

Any help would be fine.

Here is my error list and configuration file

It at least looks your linking an obj or lib that is built configured for using the static CRT, while your project is linking against the dynamic CRT. Does their SDK include a lib/dll pair that is bound to dynamic CRT ? Or did you recently change which code-generation style your project uses? — WhozCraig, Mar 06 '14 at 10:16
Lockheed Martin, don't they make weapons of war? I think answering this question would conflict with my personal ethics :-P — Simon Bosley, Mar 06 '14 at 10:36
