error LNK2001

hello, after a couple of trys i gave up! as far as i know, all environment values seems to be right. the linker is pointing on my libaries, the debuger is pointing on my binary path… everything worked well in visual studio 2008 express till now, also i had no problems or nearly no problems to compile with codegenerator MT and now i got this errrrrror???
