(3090:operation failed, error decompressing data)

Installed PGP Command Line 10.4 on new Windows 2012 server, copied over keyrings and PGPPrefs.xml file from old server, set PGP_HOME_DIR in enviroment varbles.

I can list the keys and fingerprint shows them as valid.

I can encrypt and decrypt using local keys.

When I try to decrypt a file from a thrid party, I get this error (3090:operation failed, error decompressing data)

I am able to list the packets of the file successfully, I can also dump the packets successfully.

The old server (Windows 2008R2) has no problem decrypting the files.

any ideas what I need to look for?
