You may wish to find a copy of PGP 8.0.x or 8.1. The freeware versions will get
you the key manager and clipboard functionality.

PGP anf GnuPG store 'trust' settings in different ways. PGP stores it and part
of the key; gnuPG uses a separate file. You should be able to imprt your PGP
keyring files directly into GnuPG, eg.

	gpg --import secring.skr
	gpg --import pubring.pkr

Imported key *pairs* will need to be set to Ultimate trust. This corresponds to
the 'Implicit Trust' check box in PGP's Key Properties box. Keys that were set
to Full or Partial trust in PGP will need to have those settings reapplied in
GnuPG - You can do this with WinPT or GPGshell or even the command line.

Is the key self-signed or signed by a trusted key?
