decrypting large files failes

[Daniel Musketa]

Hello,

I get the following error while trying to decrypt a file (using gnupg 
1.4.0 on Win2k):

     gpg: packet(6) with unknown version 207
     gpg: Warnung: Verschl\x81sselte Botschaft ist manipuliert worden!
     gpg: packet(1) with unknown version 22


The file size is 4.5 GB. The first part (with some gpg files only 500 
MB, with others 2 GB) is decrypted correctly.

Decrypting smaller files works fine.

Is there a size limit for creating gpg files?
