# C++ QuestionLNK4098 error that happened suddenly?

I was adding the OrbiterSoundSDK35.h/lib to my project so I can add some custom sounds. That went fine. Then I tried to add a flag for setting the thruster level to 0 if the engine state is 0. I was having trouble with that so I wanted to figure it out later. I deleted that little snippet so I can actually play with my ship. Suddenly I get this warning and every time that I start my engines (along with the sounds involved) the sound does not work. Here is the warning.

Code:
LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library

I read somewhere it has something to do with conflicts with the libraries. I haven't added any new libraries or that nature so I don't see what happened. Can anyone point me into fixing it?

Add Libcmt.lib to the "Ignore Specific Libraries" option.
