Your gpg.conf configuration contains the line

	load-extension Lib\idea

but your GnuPG directory does not contain a Lib subdirectory containing

IDEA is not included in GnuPG for patent reasons, but is available freely
for non-commercial use. The US patent expires 25-May-2010 and the European
and Japanese patents expire 16-May-2011. More information on IDEA is at
http://www.mediacrypt.com/. The lack of widespread use of IDEA shows the
chilling effect software patents can have.

If you don't need the IDEA cipher remove the line from gpg.conf.

If you do need IDEA, (ie you communicate with PGP 2.x users) obtain the
idea.dll and install it in Lib in your GnuPG program directory.

https://netfiles.uiuc.edu/ehowes/www/gpg-idea/gpg-idea.htm#120 lists two
sources for the IDEA DLL.
