[otrs] Help using PGP?

I am really new to OTRS, so far it looks great! Using OTRS v2.x I am having a bit of trouble setting up PGP. I've enabled PGP via the sysconfig menu and when I then go to the PGP config screen and try to add a key I get the following message: Info : gpg: keyblock resource `/root/.gnupg//secring.gpg': file open errorgpg: keyblock resource `/root/.gnupg//pubring.gpg': file open errorgpg: no valid OpenPGP data found.gpg: Total number processed: 0 It seems as though I need to install/configure OpenPGP first, but I really have no clue as I've never used that app before. Can anyone give me some hints on what I need to do? Thanks in advance! --Steve
