compiling errors

[Ringo]

I just reinstalled winavr and the avrcam software after not using it for a year. When I try to compile my old code using PN tools-> make all (or make clean) I get the error

> "make.exe" clean
make.exe: *** No rule to make target `C:\WinAVR\avr\include\compat\twi.h', needed by `I2CInterface.d'. Stop.

> Process Exit Code: 2

What does this mean? What am I missing?
Thanks

I got it working, I replaced the I2C files with ones from fresh source and it compiles now.
