Standard question: did you install the IDEA extension for GnuPG? If not,
make sure that PGP doesn't encrypt the file with the IDEA algorithm, or,
better, install the IDEA extension (a dll if you're running windows, a
C source file to the source and a recompile on another system).

They can be found on my site:
