[Gpg4win-users-en] Trouble importing private key

[Stephen Brown]

I have a keypair that was created in OSX that I used to sign and encrypt
mail. If I attempt to import my private, I get the following error:

C:\Users\sbrown\Desktop\keys>gpg --import secring.gpg
gpg: [don't know]: invalid packet (ctb=00)
gpg: read_block: read error: Invalid packet
gpg: import from `secring.gpg' failed: Invalid keyring
gpg: Total number processed: 0

Any ideas? I've been working on this for a couple of hours now and can't
put a finger on it....

I'm running Windows 7 Pro 64-bit and the latest version of gpg4win.

Thanks,
Stephen
