Missing file error while creating distribution

Hey,

since yesterday i get an error every time i try to build a distribution. The error says "*** Error (-32): A file, directory, or other data could not be found."

A few month ago the build worked find and i think i don't changed anything. I also tried with another project, but the same error occurs. I am using CVI 2012.

So, could someone help me?

Thanks, Stefan
