Strange problem when using GPG

Dear GPG users,

I have a small problem which seems to get a little bit out of control
;) I'm using a DSS/DH key, generated with GPG 1.06 on Windows 2000,
with the KeyID 0xADCF7E94[1].

I receive a message, encrypted to this key. GPG, both on Windows and
Unix platform[2] give me an error when trying to decrypt this message:

> draenor:~# gpg -d decrypt.asc
> gpg: encrypted with ELG-E key, ID 900227D4
> gpg: encrypted with ELG-E key, ID 1BE6477F
> gpg: decryption failed: secret key not available
> draenor:~#

And as well on Windows:

> C:\>gpg -d decrypt.txt
> gpg: encrypted with 2048-bit ELG-E key, ID 900227D4, created 2002-06-20
>       "Martin F. Krafft (Debian) <madduck@debian.org>"
> gpg: encrypted with 2048-bit ELG-E key, ID 1BE6477F, created 2002-12-24
>       "Johannes Posel (GnuPG Key) <jmp@its-toasted.org>"
> gpg: decryption failed: secret key not available
> C:\>

But the secret key is there, and signing etc works flawlessly:

> C:\>gpg --edit-key ADCF7E94

Thanks for any tips on what could be wrong!

Cheers,
