Log without the crypto patch

Here's the log without the above patch.  The game first calls
CryptMessageVerifySignature with a NULL pcbDecoded to find out the decoded
message size, then allocates a buffer for it and calls again.  However, since
pcbDecoded is cleared in the beginning, the rest of the function will think the
buffer is zero bytes long and doesn't have enough space to copy the message in.
