[racket] file will not read into the program

I'm using DrRacket as an accompanying material for the HtDP book. I'm
learning it by myself, not as a part of a schooll assignment.

I have a problem with the exercise 2.2.1 - when I run the convert-file
program it doesn't want to accept the input file, the error message I get

> (convert-file "file.in" Fahrenheit->Celsius "out.dat")
convert-file: expects a name of existing file in c:\users\jakub
hadam\documents\drracket\ as first argument, given "file.in"

I've made sure the file is in the specified folder, but DrRacket seems to
refuse to see it. I would be thankfull for any help and sugestions.

(I have no problem running convert-gui and convert-repl. I use the
"Beginning Student" language. The OS is Win7Premium)

Thanks a lot for your help.
