Problem Encrypting with RSA and Crypto++ 3.1

Hi All,
  I have tried to write a very simple encryption routine with the SFL
and I'm getting "Assertion failed: modulus.IsOdd(), file
..\crypto31\integer.cpp, line 2250 with the code below when encrypt is
called. I would really appreciate help in getting this to work! :) I
have spent several days trying different things. The one thing that sort
of works (i.e. it doesn't crash) is to use a DSA cert for the login but
then it won't let an RSA cert be a recipient!

TIA
-Jonathan
