Can't compile/clean CUDA projects

For whatever reason I can’t compile, or even clean a project in visual studio 2013 which uses CUDA. The project, the code should be 100% working, cause it is working on a friend’s computer. When I try to clean or compile I get the following error:

Error 1 error MSB3721: The command ““C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\bin\nvcc.exe” -ccbin “C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin” -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0/include” -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\include" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\include" --keep-dir Release -maxrregcount=0 --machine 32 --compile -DWIN32 -DNDEBUG -D_CONSOLE -D_LIB -D_UNICODE -DUNICODE -Xcompiler “/EHsc /W3 /nologo /O2 /Zi /MD " -o Release\ “e:\Doks\egyetem\MSc 4 felev\gpgpu\beadandok\cuda\weiszfeld\weiszfeld\” -clean” exited with code 1. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\CUDA 7.0.targets 759 9 weiszfeld

I have absolutely no idea what is going on, it compiled fine an hour ago, and now it just gives me this. I tryed all possible linker settings, I even reinstalled CUDA. Anyone has any idea what’s going on?
