Hi Gloria,

Thanks for reporting this problem. Looking at the source code, it seems that this error can only occur if ~/Desktop/kdHydrophobicity.txt is an empty file, so you should look at its contents and make sure it contains what you think it contains.
I have changed the code so that it produces a message that the file is empty rather than an error, and that code will be in tomorrow's build.
